If a cell has 20% Adenine in it, what % of Cytosine must it have?
A
10%
B
20%
C
30%
D
80%
Explanation: 

Detailed explanation-1: -Answer: There would be 20% Cytosine. Adenine (30%) = Thymine (30%) Guanine (20%) = Cytosine (20%)

Detailed explanation-2: -Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.

Detailed explanation-3: -If 20% of the DNA in a guinea pig cell is adenine, what percentage is cytosine? Explain your answer. If 20% is adenine, then 20% is thymine. The remaining 60% is composed of cytosine and guanine in equal percentages so that each makes up 30% of the DNA.

Detailed explanation-4: -If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%.

Detailed explanation-5: -A strand of RNA is composed of 20% adenine and 30% guanine.
