Question

If a 10 base-pair long DNA molecule consists of 30% Thymine, how many of each of the 4 different nucleotides is present

Answer 1

Step-by-step explanation:

Based on Chargaff's Rule:

There is the same amount of Adenine (A) as Thymine (T) and there is the same amount of Guanine (G) as Cytosine (C)

30% of 10 = 3 There are 3 Thymines (T) , so there are 3 Adinines (A)

10 - (3 + 3) = 4

There are 2 Guanines (G) and 2 Cytosines (C)
