Question

If a double stranded DNA has 20 percent of cytosine calculate the percent of adenine in the DNA


​

Answer 1

Explanation:

Thus, if a double-stranded DNA has 20% cytosine, it has 20% guanine. Thus, C + G makes 40% of the total bases. The remaining 60% includes both adenine and thymine which are in equal amounts. So, the percentage of adenine is 30%.

Answer 2

In a DNA molecules the number of cylosin molecule is equal to guanine molecules and the number of adenine molecule is equal to thymine molecule. Thus, if a double stranded DNA has 20% cytosine, it has 20% guanine.

Thus C+G make 40% of the total bases. The remaining 60% includes both Adenine and thymine which are in equal amounts. So the persentage of ADENINE IS 30%
