Question

Point mutation is

• B. Change in a base of gene
• C. Addition of a gene
• D. Deletion of a segment of gene

Answer 1

The correct option is B Change in a base of gene

A point mutation is a type of mutation in DNA or RNA, the cell's genetic material, in which one single nucleotide base is added, deleted or changed. A point mutation is specifically when only one nucleotide base is changed in some way, although multiple point mutations can occur in one strand of DNA or RNA.

So, the correct answer is 'Change in a base of gene'
