Question

If the total amount of adenine and thymine in a double stranded DNA is 60%.what will be the amount of guanine in this DNA????

Answer 1

Since Adenine binds with cuisine, the amount of A will be equal to amount of T.

Thus, you can obtain the no. A and T by dividing their combined amount by 2. (60/2=30). Thus the amount of A and T are both 30% respectively.

Now by Ervin chargaff's rule we know that A, T, G and C together form 100% of the DNA.

so, by subtracting the amount of A and T, we get the amount of G and C, which is 40% (100–60=40).

Similarly there will be equal amounts of G and C present so, we can conclude that the amount of G is 20% (40/2=20).

Answer 2

Answer:

Explanation:

If the amount of adenine+ thymine = 60%, then the amount of guanine + cytosine will be 40%. So, the amount of guanine in this DNA will be = 20%.Oct 15, 2019
