Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA really stands for Deoxyribonucleic acid. DNA is a right handed double helix. Nucleotides that mount together by phosphodiester bonds make up DNA. It also contains a spiral strand that is made of phosphate backbone and secure bases (Adenine‚ Guanine‚ Cytosine‚ Thymine). Cytosine and Thymine are Pyrimidines‚ while Adenine and Guanine are Purines.

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 right

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information‚ composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The
