In the DNA chain, thymine is 20%. Find how much adenine and cytosine?

Since thymine in DNA is complementary to adenine (its amount is equal to the amount of adenine), then adenine is also 20%
Then the total in the DNA of thymine and adenine is 40%
The remaining 60% is cytosine and guanine, but they are complementary to each other, which means they are equally divided
And then cytosine is 30%
Answer: adenine 20%, cytosine 30%
