Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
DNA replication is semi-conservative, a type of replication, in which one strand of the daughter duplex is derived from the parent while the other strand is formed new. This is carried out by the separation of two strands. The separated strands function as templates.The new strands built up over the templates of old strands will have complementary base pairs (A opposite T and G opposite C).
The two daughter DNA molecules thus formed will be carbon copies of the parent molecule but shall have one new strand and one old strand.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is not the correct explanation for Assertion'
