A segment of DNA, AGCTTCGAA, has lost first base. Assuming that translation starts from the next base the effect would be

A

No change in polypeptide form

B

Only first amino acid will be different

C

A complete change in type and sequence of amino acids

D

Last amino acid of polypeptide will be different

Text Solution

Verified by Experts

The correct Answer is:
C

A segment of DNA, AGCTTCGAA, has lost first base. Assuming that translation starts from the next base the effect would be a complete change in type and sequence of amino acids as genetic code reads in a contiguous manner.
