Given below is a sample of portion of DNA strand given the base sequence on the opposite strand. What is so special show in it?

5’−GAATTC….3’

3’−CTTAAG … 5’

  • Detection mutation

  • Start codon at 5′ end

  • The palindromic sequence of base pairs

  • Replication completed

The palindromic sequence of base pairs

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