View written solutionFree

Correct answer: A

A palindromic sequence is a nucleic acid sequence (DNA or RNA) that is the same whether read 5' (five-prime) to 3' (three prime) on one strand or 5' to 3' on the complementary strand with which it forms a double helix.
5' - GAATTC - 3'
3' - CTTAAG - 5'
It is a palindromic sequence of DNA cut by restriction enzyme Eco RI.
