Q. The specific DNA sequence recognised by EcoRI is

NTA AbhyasNTA Abhyas 2020Biotechnology : Principles and Processes

Solution:

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.
