Assertion : If the sequence of bases in ...

Assertion : If the sequence of bases in one strand is known then the sequence in other strand can be predicted.
Reason : Both the strands of DNA are complementary of each other.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
The base pairing confers a very unique property to the polynucleotide chains. They are said to be completmentary to each other, and therefore if the sequence of bases in one strand is known then the sequence in other strand can be predicted.
