Question

Which of the following causes point mutation?

• A. Deletion
• B. Inversion
• C. Both A and B
• D. None of the above

Answer 1

The correct option is A Deletion

Mutation in single nucleotide base of a DNA segment is called as point mutation. Removal of one or more nucleotide bases to the DNA segment is known as deletion. Deletion of single nucleotide causes point mutation. Inversion is chromosomal mutation where a segment of a chromosome is reversed end to end. Inversion disturbs a comparatively large chromosomal and introduces chromosomal aberrations but not point mutations. Thus, the correct answer is option A.
