Question

A sample of DNA was tested to find its bases. It was found that it has 30% T. what person of the DNA would you expect for base A . Explain your answer​

Answer 1

Answer:

According to the rule given by Chargaff, A + G = C + T.

Adenine (A) will always pair with Thymine (T). This means that A = T.

Cytosine (C) will always pair with Guanine (G). This means that C = G.

Since the proportion of thymine T = 30%, so, A = 30%.

G + C = 100 - 60% = 40%

So, G = 20% and C = 20%.

Therefore, the answer is T = 30%, A = 30%, G = 20% and C = 20%.
