REPLICACION
La replicación exacta del DNA cromosómico es un fenómeno esencial preliminar a la reproducción la replicación se realiza por un mecanismo semiconservador y cada nueva molécula de DNA esta formada por una hebra del DNA progenitor y la hebra hija. la síntesis de DNA se lleva acabo por la acción de la DNA polimerasa especificas que utilizan como molde el DNA existente. En los procariontes sólo parece requerirse un tipo , la DNA pol III para copiar el molde, no obstante, en los eucariontes hay varias enzimas polimerasas activas que intervienen en la síntesis, también intervienen otras proteínas en la síntesis del DNA tanto en los procariontes como en los eucariontes.

Dna Replication

...DNA Replication 1. DNA Replication take place by breaking the hydrogen bonds between bases of the two antiparallel strands. The unwinding of the two strands is the starting point. 2. Helicase (enzyme) splits the two strands. The initiation point, where the splitting starts, is called “origin of replication”. The structure that is created is known as “Replication Fork”. 3. Molecules of single-strand binding protein stabilize the unwound template strads. 4. Topoisomerase helps relieve the strain by breaking, swiveling, and rejoining DNA strands. 5. RNA Primase (enzyme) binds in the initiation point of the 3’ – 5’ parent chain. It can attract RNA nucleotides which bind to the DNA nucleotides of the 3’ – 5’ strand due to the hydrogen bonds between the bases. RNA nucleotides are the primers (starters) for the binding of DNA nucleotides. 6. DNA Polymerase III (enzyme) link up the free, matched nucleotide triphosphates by removing the terminal di-phosphate and using energy so released to carry out the very non-spontaneous chemical reaction of joining the phosphate to the deoxyribose sugar. 7. The strand that is synthesized continuously is called the leading strand and the strand that is synthesized in short pieces is called the lagging strand. The short pieces of synthesized DNA, which make up the lagging strand are called the Okazaki fragments. 8. Only one primer is required for DNA Polymerase III to synthesize the leading strand. 9.

Dna Replication

...DNA replication Name Institution 16th November, 2015 DNA DNA stands for deoxyribonucleic acid. Every strand of DNA is comprised of a sugar, a phosphate and a nitrogenous base fortified together into a structure called a nucleotide. Several nucleotides together form DNA. DNA Replication The DNA double helix is typically extremely stable: the two DNA strands are bolted together immovably by an expansive number of hydrogen bonds framed between the bases on every strand. To be utilized as a format, the twofold helix should first be opened up and the two strands isolated to uncover unpaired bases. In DNA replication, two strands of DNA separate, and every different strand shapes a layout to make another strand. The replication procedure results in the development of two indistinguishable particles, containing one strand from the first bit of DNA and one recently incorporated strand. DNA contains all guidelines for making protein in the body and information around a man's physical attributes, for example, eye shading and hair shading. The protein in a DNA atom is encoded by a gene, which determines the sorts of amino acids that must be assembled to make a protein. In DNA replication, there is an arrangement of single-stranded tying proteins that are utilized to balance out the isolated strands. The DNA replication procedure begins with the cells utilizing what is termed a "protein machine" called the "Origin Recognition Complex" or ORC. The ORC starts as a bow-shaped protein...

...DNA Replication, Translation, Transcription, and Death Cap Mushrooms Biochemistry – GRT1 Task 1 02/14/2015 (Wolfe, DNA Replication, 2000) (Wolfe, DNA Translation, 2000) A death cap mushroom, also known as Amanita phalloides, is a poisonous mushroom that can be detrimental to our health. When a death cap mushroom is ingested a toxic substance known as alpha amanitin is released into the body’s system. This toxin prevents protein production and leads to cell death (Santi, Luca, Caterina Maggioli, Marianna Mastroroberto, Manuel Tufoni, Lucia Napoli, and Paolo Caraceni, 2012). RNA polymerase, the enzyme responsible for synthesizing mRNA, is the enzyme directly affected by alpha amanitin. Alpha amanitin blocks RNA polymerase from working properly within the cell (Hudon-Miller, 2013). Without RNA polymerase, mRNA is not transcribed from DNA. Without mRNA, ribosomes cannot complete translation to form polypeptides, also known as proteins (Hudson-Miller, 2013). Proteins provide the necessary means to keep cells functioning accordingly. The liver and kidneys are the organs targeted by this toxin as they are the filtering system of the body and this toxin will enter their cells (Hudson-Miller, 2013). With RNA polymerase inhibited, no ability to produce proteins, the ultimate effect of this toxin has been reached and cell death occurs. References Hudon-MIller, S. (2013). Death cap mushroom.

...Abstract There were many causes of the Great Depression, some of which include “The Great Crash” of the stock market, lack of spending by the average person, the Smoot-Hawley Tariff Act and a massive drought in the Mississippi Valley. From this nation-wide crisis came Social Security as we know it, the creation of the Tennessee Valley Authority Act, the creation of the SEC and stricter banking and stock market regulations. Overall the Great Depression had a large impact on The United States that can still be seen today. Causes of the Great Depression In January of 1929 an editorial (Encyclopedia of American Studies, 2010) said “It has been twelve months of unprecedented advance, of wonderful prosperity. If there is any way of judging the future by the past, this new year will be one of felicitation and hopefulness.” This was obviously not the case. When the stock market crashed on October 29, 1929, it was possibly the greatest contributing factor to the depression. Some believe, though incorrectly, that the “Great Crash” is the same as the great depression. The stock market crash had people scared to spend money. People no longer bought nearly as many products which led to a drop in production, which in turn led to layoffs in the work force. Coupled with these layoffs, were huge debts being defaulted on by stock holders; this all inevitably to the failure or closing of many banks. The Smoot-Hawley Tariff Act was passed in June 1930 to protect...

I remember saying these exact words after finding out that my grandmother had been diagnosed with cancer, this was about seven years ago. When she was first diagnosed with cancer, she made sure that the whole family knew right away and this took a toll on my family. Before this had all happened, my Yiayia, Greek for grandmother, knew she had multiple myeloma she complained about having back pain. We just assumed it was from her osteoporosis, which causes bones to become fragile (Osteoporosis Mayo Clinic Staff, 2014). Little did we know what was happening to my grandmothers body, a good family friend, Dr. Cleo Williams, recommend that she go to the doctors to get a compression fracture, which is caused by osteoporosis, and for cancer (Boden, 2005). Not long after the consult, she went to the doctors to have surgery for the compression fracture to prevent further pain that, “usually occurs in the front of the vertebra, collapsing the bone in the front of the spine and leaving the back of the same bone unchanged” (Boden 2005). While, the doctors were doing the compression fracture surgery they looked further into her spine and found she had early stages of multiple myeloma. The doctors then ran every test possible to see where the cancer cells were, so...

What in You Water Bottle

...chemicals used to make plastic containers are a health hazard to humans. A particular focus is placed on whether the chemical ingredient in polycarbonate and polysulfone plastic called Bisphenol A, BPA abbreviated, act as estrogen and effect estrogen levels. Research is continually being conducted since possibly harmful BPA is found in almost 90% of plastic containers ( ). Although many shelved plastic products are labeled BPA-Free, plastic containers still run the risk of leaking harmful BPA into drinking water and food when BPA is broken down by exposure to heat ( ). Research has not yet proven how BPA is harmful; That is to say, definitive results have not shown whether BPA directly causes cancer, or if BPA is a catalyst for cancer cell replication. Regardless of how BPA is harmful, the possibility of poisonous contamination to all plastic exposed products poses a threat to human health and has resulted in case studies like Mclean’s “What’s in My Water Bottle?” Mclean’s case study addresses multiple experiments that are conducted to determine how much BPA is in certain plastics, and how the BPA effects estrogen levels that in turn effect cancer cells, reproductive organs, and lipid metabolism. In 1976 the Safe Drinking Act was passed setting limits on the amount of contamination that could enter the public drinking supply ( ).Thus, consumers trustingly eat and drink from plastic containers daily, and only research on the possibility of harmful contamination can protect and...

Dna Reproductive Process

...When the two strands of DNA double helix are separated, each can serve as a template for the replication of a new complementary strand, producing two daughter molecules each of which contains two DNA strands with an antiparallel orientation. The enzymes involved in DNA replication process are template-directed polymerases that can synthesize the complementary sequence of each strand with extraordinary fidelity. This complex leads to the local denaturation and unwinding of an adjacent A + T rich region of DNA. The interaction of proteins with the origin is what defines the start site of replication and provides a short region of single stranded DNA essential to initiation of synthesis of the nascent DNA strand. Then helicase binds and allows for processive unwinding of double stranded DNA into single stranded DNA. As helicase unwinds the DNA, DNA single stranded protiens bind and stabilize the single stranded DNA. The polymerase III holoenzyme binds to template DNA as a part of a multi protein complex that consists of several polymerase accessory factors. DNA polymerase synthesizes DNA only in the 5 ' to 3 ' direction and only one of the several different types of polymerases is involved at the replication fork. As the DNA strands are anti parallel, the DNA polymerase functions asymmetrically. On the leading (forward) strand, the DNA is synthesized continuously. On the lagging strand (retro strand) the DNA is synthesized in short (1-5 kb) fragments. These DNA fragments are called...

Biochemistry

...DNA Replication Jennifer Wilson Biochemistry GRT1 Margie Hayes January 18,2015 Deoxyribonucleic Acid (DNA) DNA is made of chemical building blocks called nucleotides. These building blocks (nucleotides) are made of phosphate, sugar and one of four types of nitrogen bases. The four types of nitrogen bases found in nucleotides are: adenine, thymine, guanine and cytosine. These nucleotides are either purine or pyrimidine based, called nucleotide subunits. The purine base are adenine and guanine. The pyrimidine based are thymine and cytosine. The DNA strand is formed when the nucleotides are linked into chains, with the phosphate and sugar group alternating. As you can see in the diagram above, adenine bonds with thymine and guanine bonds with cytosine. These bonds take place by hydrogen bonding. DNA Replication Fork Topoisomerases are enzymes that regulate the overwinding or underwinding of DNA, shown as the yellow wire above. Topoisomerases catalyze and guide the unknotting and unkinking of DNA. The double-helical configuration that DNA strands naturally reside makes them difficult to separate, so they must be separated by helicase enzymes. Helicase separates the strands of a DNA double helix by using the energy from ATP hydrolysis so replication can begin. The replication bubble allows replication to take place in 2 directions. Primase is an enzyme that synthesizes short RNA sequences called primers. These primers are the starting point for DNA synthesis at...
