Question

Which of the following is not a type of chromosome mutation?

• A. Duplication
• B. Inversion
• C. Deletion
• D. Frame shift

Answer 1

The correct option is D Frame shift

Chromosome mutation is a change in the structure of the chromosome, leading to abnormalities.

Frameshift mutation is not a chromosomal mutation instead it is a genetic mutation in which the reading frame of DNA shifts due to addition or removal of gene. Hence the frame for reading codon shifts by a unit and codes for different protein.

Hence, option D is correct.
