Question

During analysis of the DNA of an organism having
5386 nucleotides find out A= 29%, G = 17%, C = 32%,
T= 17%. Considering the Chargaff's rule it can be con-
cluded that
(A) It is double stranded linear DNA
(B) It is double stranded circular DNA
(C) It is single stranded DNA
(D) Both A and B

Answer 1

Answer:

C) It is single stranded DNA

Explanation:

For a double stranded DNA molecule, Chargaff rule is valid.

First we have to check whether Chargaff rule if followed or not.

Acc. to Chargaff rule,

A=T and G=C

But in this ques, there are different percentages.

So it cannot be a double stranded DNA.

So answer is single stranded DNA
