If 27% of the bases in a certain segment of dna were adenine, what would be the percentage of (hints: which base will have the same percentage as adenine? all four should add up to 100%):
a) thymine -
b) cytosine -
c) guanine -

A)- 27% because adenine and thymine always pair together so they will be equal to each other
b) and c) each will have 23% because cytosine and guanine always pair so they will be equal to each other
23% cytosine + 23% guanine + 27% Thymine + 27% adenine = 100%
