Assertion : The two strands in DNA are complementary.
Reason : Cytosine always pasirs with guanine and thymine with adenine.

Why does cytosine make pair with guanine and not with adenine ?

Assertion (A): The DNA has two complementary strands. Reason (R): Adenine always pairs with thymine and guanine with cytosine.

Why adenine always pairs with thymine and guanine with cytosine ?

Assertion: The two strands of DNA are complementary to each other Reason: Adenine specifically forms hydrogen bonds with guanine whereas cytosine forms hydrogen bonds with thymine.

Assertion: The two strands of DNA are complementary to each other Reason: Adenine specifically forms hydrogen bonds with guanine whereas cytosine forms hydrogen bonds with thymine.

Assertion :- Thymine is one of the DNA bases. Reason : Complementary base of guanosine is thymine.

Which one is the complementary base of cytosine in one strand to that in other strand of DNA?
