LAB#11 DNA EXTRACTION & KARYOTYPING ________________________________________________ Objectives: After completing this exercise, you should be able to: 1. Develop an understanding of the structure and properties of DNA, based on observation and manipulations 2. Understand some implications of DNA technology 3. Extract DNA from an onion to understand that all cells contain DNA Introduction/Purpose: DNA is too small to see under a regular microscope, so then how can it

Extraction of DNA from an Onion Molecular biologists and biochemists are involved with research in finding out as much as possible about the DNA in plants and animals. Although DNA was discovered in the 1950’s, there still remains a lot to be known about it, especially how it is used to determine the physical traits that we all have, and how it regulates the workings of the body. We should always remember that DNA is just a chemical named deoxyribonucleic acid. Because it is a chemical, we

Pepper Seed DNA Extraction Biochem lab: CHE 452L marisol gomez Pepper Seed DNA Extraction Biochem lab: CHE 452L marisol gomez 2015 2015 INTRODUCTION The jalapeno is a member of the capsicum family, along with many other peppers. The usual methods for characterization of different pepper species are based on their morphological and physiological traits, however this many not always be enough. For peppers, their traits are influenced by things like their genotype or their specific environment

Title: Extraction of genomic DNA Introduction: Isolation of genomic DNA is one of the most commonly used practices in several areas of science. Purified, high molecular weight DNA is used for many applications such as: * To prepare genomic DNA libraries * To isolate genes to be cloned * To carry out southern blotting and hybridization Many different methods are available for isolation of genomic DNA, and they all involve the following basic stages

Tooth loss and dental extractions have existed for centuries with the latter being the main tool for providing relief from dental pain and removing diseased tissues (Torabinejad). There was an estimated 50 million dental extractions performed in the United States in 1979 (Bullock). With the increased number of people living in the United States for a longer period of time, the occurrence of dental extractions and tooth loss has certainly risen exponentially. Unfortunately, tooth loss, whether

Purpose To examine the microbial population of an elliptical at the Dixon Recreation Center by analysis of DNA from an uncultured community sample. 16S rRNA genes will distinguish bacteria and represent the microbial diversity of the sampled elliptical. An estimate of the cleanliness of the elliptical will be made based on species-abundance as well as evidence of any pathogenic strains. We will also compare and contrast respective populations of bacteria on clean and disinfected ellipticals to assess

DNA Technology BIO/240 May 6, 2013 DNA Technology INTRO – LEE DNA Technology: Cloning, Gene Therapy, and Stem Cell Research DNA technology encompasses a wide variety of applications and because of the duplicating nature of DNA, it is easy to see how humans could benefit from its manipulation. One such technology is cloning. Cloning technology comes in three forms: recombinant DNA cloning, reproductive cloning, and therapeutic cloning. Cloning Recombinant DNA cloning consists of transferring

Laboratory Exercise #8 DNA Fingerprinting: Identification of DNA Restriction Fragmentation Patterns I. Introduction All humans have in common the coding sequences of their DNA, but, unless you are an identical twin, the non-coding sequences of your DNA are like no other person’s on the planet. The bulk of human DNA does not code for specific genes and is highly repetitive. A British geneticist, Alec Jefferies, developed laboratory techniques in 1984 that became known as DNA fingerprinting. These
