Document Summary

3" and 5" ends - the back bone has a 3" end and the other is a 5" end, the two strands are lined up opposite to each other. The 5" end contains a phosphate molecule and the. Adenine - one of the four nitrogenous bases. Adenine is a purine that is a larger nitrogenous base. Base pairs - adenine and thymine, guanine and cytosine. The combination of these insures that the distances between the two strands will always be the same. Purines (a and g) are much larger than the pyrimidines (t and c). Complimentary strand - strand of dna that is built using an original strand of dna as a template. The complimentary strand has pairing nucleotides, and requires a few nucleotides at the begging to allow it to start building. Then rna polymerase comes and builds the new dna strand. Cytosine - one of the four nitrogenous bases.
