Transcript of DNA Structure

The Structure of DNA!! Nucleotide Also known as a 5-carbon sugar (deoxyribose) Nitrogen containing bases:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T) Adenine and guanine are purines, which are the larger types of bases found in DNA Cytosine and thymine are pyrimides, which are the smaller types of bases found in DNA DNA's molecular structure is called a double helix Deoxyribonucleic acid First, the deoxyribose binds with phosphate at both its 3' (three prime) and 5' (five prime) carbons When they bind they create phosphodiester bonds, which join millions of subunits into a single strand. Thus creating the backbone of the DNA Next, the genetic information is encoded in the sequence of bases attached to the 1' (one prime) carbons of the sugars The sequence of the bases in DNA is called the genetic code Lastly, every strand of DNA is hyrogen-bonded to a second strand whose bases go along with the first strand. Example: A bonds with T and G bonds with C The hydrogen bonding is what twists the two strands into a helix There are four different nitrogen containing bases in DNA Adenine is always matched up with thymine and guanine is always matched up with cytosine in DNA Nitrogenous bases is either A,T,C,G There are three parts to a nucleotide Phosphate The five carbon sugar has five sides that are important to know about when talking about the formation of DNA is formed. These sides are the 1,2,3,4, and 5 prime sides During the creation of DNA, only one strand of it is made at a time. One strand of DNA looks something like this Once two corresponding stands are created they join together with hydrogen bonds and twist creating a double helix. Here is a quick overview of how DNA is created After this step one strand of DNA is complete
