Question

Assertion : Sequences of bases in one polynucleotide chain of DNA can determine the sequence of bases in the other chain Reason : A=T ans C-G .

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

B) if both the assertion and reason are true but the reason it not a correct explaination of the assertion

C) if the assertion is true but the reason is false

D) if both the assertion and reason are false

E)
if the assertion is false but reason is true​

Answer 1

A is the answer

Although A = T and C º G, there is no any restriction or sequence of bases in one polynucleotide chain. Since A is always linked to T and C to G as determined from the above evidences, sequence of bases in one of polynucleotide should determine the sequence of bases in the other polynucleotide of the double helix.
