Answer: B. Full step-by-step solution below.

  1. AOkazaki sequences
  2. BPalindromic Nucleotide sequences
  3. CPoly (A) tail sequences
  4. DDegenerate primer sequence

Correct answer: B

Solution

(b) Each restriction endonuclease enzyme recognises a specific palindromic nucleotide sequence in the DNA and bind to the DNA. Then, the enzyme cut each of the two strands of the double helix at specific points in their sugar-phosphate backbones.
