According to Chargaff's rule, the amount of purines is equal to the amount of pyrimidine in a DNA. Therefore, in an analysis of the number of different bases in a DNA sample, A+G=C+T, will be consistent with the base pairing rules.
1. Adenine must be 25% in this question it's given as 20%, as per basic rule given above. T will be 25
2. C is 25 %
3. There will be 2 hydrogen bonds between A and T, and 3 hydrogen bonds between C and G

You have a piece of double stranded DNA that is 300 base pairs and 50% guanine remember there are 2 nucleotides in a base pair 1, How many H bonds hold the strands together? 2. How many purines are in the molecule? 3. How many pyrimidines in this molelcule? 4 Would you expect this strand to "melt" at a higher or lower temperature than AT rich DNA?

(b) the two strands of DNA are held together in the double helix form by hydrogen bonds between complementary base pairs. What is a hydrogen bond? (c) Suppose a new disease appears that creates covalent, rather than hydrogen, bonds between the two strands of DNA (this is VERY unlikely!). If you had to design a drug to combat the disease,...
