Given below is a sample of portion of DNA strand giving the base sequence on the opposite strands. What is so, special shown in it? 5^ _ GAATTC __ 3^ 3 - CTTAAG 5^

Options

  1. ADeletion mutation
  2. BStart codon at the 5^ end
  3. CPalindromic sequence of base pairs
  4. DReplication completed

Correct answer

C. Palindromic sequence of base pairs

Step-by-step solution

Palindromic DNA is a base sequence of DNA, which reads the same forward or backward. It has similar sequence in both the strands. Different types of palindromic sequences are recognised by restriction endonucleases.
