WebThere are two kinds of nitrogen containing bases – the Purines and Pyrimidines. Purines (Adenine and Guanine) are both present in DNA and RNA and have two-ring structure while pyrimidines in DNA are Cytosine and Thymine, in RNA are Cytosine and Uracil have only one ring. Nitrogen bases are held together by hydrogen bonds. WebQuestion: The two DNA chains in a double helix wind around each other in such a way that purines are always opposite pyrimidines and vice versa are parallel to each other in 5' to 3' directionality have identical base sequences are held together due to the charges of their phosphate groups FISH can be used to determine the locations of major and …
