Question

Which of the following is the correct matching nucleotide sequence for CTAGG? The choices are the following: CTAGG. GATCC. GGATC. AGCTT

Answer 1

The correct answer is- GATCC

Step-by-step explanation:

According to the rule of base pairing or Chargraff's rule purine always base pairs with pyrimidines and pyrimidines base pairs with purines. So according to the nucleotide complementarity adenine base pairs with thymine and thymine with adenine with two hydrogen bonds and guanine base pairs with cytosine and cytosine with guanine with three hydrogen bonds.

So the correct matching nucleotide sequence for CTAGG would be GATCC according to the complementary base pairing. In RNA thymine is replaced by uracil nucleotide. So uracil makes complementary base pairing with adenine in RNA.

Answer 2

GATCC is the correct matching nucleotide sequence for GATCC. The correct answer between all the choices given is the second choice or letter B.
