Question

The specific DNA sequence recognised by EcoRI is (A) 3' GAATTC 5' (B) 5' GAATTC 3' (C) 5' GTTAAC 3' (D) 3' GTTAAC 5'

Tardigrade Admin · Accepted Answer

EcoRI recognizes the sequence 5' GAATTC 3' in double-stranded DNA. This recognition sequence is a palindrome with a two-fold axis of symmetry because reading from 5' to 3' on either strand of the helix gives the same sequence.
