Restriction enzymes cleave double-stranded DNA at the sites that show a particular type of symmetry: These sequences read the same on both strands and are called palindromes. Which of the following sequences is NOT a palindrome?
A) 5′-AGATCT-3′
B) 5′-CCTGCAGG-3′
C) 5′-CCTCAGG-3′
D) 5′-CGGCCG-3′
E) 5′-GGTACC-3′

Respuesta :

Answer:

The correct answer is C) 5"-CCTCAGG-3"

Explanation:

Palindromic sequence is a that remain same when read from front side as well as from the back side.

     Such as MADAM,ROTOR

In the given question option C is not a palindromic sequence beacuse when we read from frontside it is

        5"-CCTCAGG-3"

But when we this this same sequence from the backside it becomes

      5"CCTGAGG-3"
