Given below is a sample of a 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'

  • Deletion mutation

  • Start codon at the 5'end

  • Palindromic sequence of base pairs

  • Replication completed

Answer

C.

Palindromic sequence of base pairs

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.
