Question

if adine is 20 % than what %of cytocine

Answer 1

If thymine is 20% so as the adenine is also 20%, because asinine always pair with thymine therefore the percentage of adenine and thymine is 20+20 = 40%, thus the remaining 60%is of guanine and cytosine.

If cytosine is 30% then the percentage of guanine is also 30% because guanine is always pair with cytosine.
