Biology

Viktor [21]3 years ago

Answer:

Explanation:

According to Erwin Chargff's rule, he stated that, adenine (a purine) always forms base pairs with thymine (a pyrimidine) and that guanine (a purine) always forms base pairs with cytosine (a pyrimidine). an adenine does not form base pairs with cytosine despite it being a pyrimidine.

thus the amount of adenine will always be equal to that of thymine while

the amount of guanine will always be equal to that of cytosine. Therefore, since we have 22% of adenine, the amount of thymine will also be 22% making a total of 44%. thus to find the amount of guanine and cytosine = 100-44= 56%.

the amount of guanine will thus be 56/2= 28%, since guanine and cytosine are of equal amount.
