Principle Of Inheritance And Variation Question 562
Question: Assertion : Sequences of bases in one polynucleotide chain of DNA can determine the sequence of bases in the other chain Reason : A = T and C - G.
Options:
A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
Show Answer
Answer:
Correct Answer: B
Solution:
Although A = T and C ΒΊ 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.
