If a gene is made up of 20% adenine, how much thymine, guanine, and cytosine will there be

Explanation:

  You have 20% of adenine. 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%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

it supports cell theory.it states that all living cells are made from cells

i believe it would be c: tons.
