Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is composed of two polynucleotide strands wound together into a structure known as a double helix. Each nucleotide consists of a sugar base .Nucleotides form together creating a sugar phosphate backbone to each strand. There are three forms of DNA that differ significantly. The most common, B form, is the structure most people have heard of. It consists of the

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides, each attached to the one immediately about it and the one immediately below it to form a long chain. Each

DNA Mutations- The Consequences Introduction Deoxyribonucleic acid, which is more commonly known as DNA, is the hereditary material in almost all organisms. Its purpose is to store and retain the genetic information needed to be able to construct as well as maintain an organism such as a human being. Due to this people like to say that it is seen as the blueprint of life, as it contains the instructions for everything a part of you, such as eye color, height, hair type and several more. It

For this assignment, we were asked to go on a site called Gizmos and use the simulation on the site to fill in our answers on our worksheet. The assignment was about cell division and the different stages of the cell cycle. We were expected to be able to complete the assignment completely with no blanks on our papers. We were also expected to answer in full sentences to receive an “A”. This particular assignment is similar to others we have worked on because like other class works, we had to experiment

Problems from textbook 13.18 The streptomycin sensitive strain should be exposed to a mutagen (such as UV light or radiation) to create mutants that may be resistant to streptomycin. Next, prepare a plate that has streptomycin. The bacterial colonies that grow on this plate will all be resistant to streptomycin. Now, make a copy of these colonies using replica plating. Transfer the colonies to a plate that does not contain streptomycin. The colonies that grow on the plate without streptomycin
