Question

The dna of a cell is analyzed and found to contain 28 percent thymine. what percent of the dna would by cytosine?

Answer 1

Answer: 22% Cytosine
If Thymine is at 28% and Thymine always pairs with Adenine (another compound that is one of four constituents of nucleic acids, often paired with Thymine in double-stranded DNA), then Adenine is also 28%. The remaining 44% will then be divided between Cytosine and Guanine (another compound) since they also form pairs.
