Question

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'

• A. Mutation detected
• B. Start codon at 5' end
• C. Palindromic sequence of base pairs
• D. Replication completed

Answer 1

The correct option is C Palindromic sequence of base pairs

Palindromic sequences are the one which is read same forward and backward. It is a nucleic acid sequence (DNA or RNA) which is read same from 5' to 3' on one strand and 5' to 3' on its complementary strand and hence can be cut easily.

Thus, the correct answer is option C.
