Question
Point mutation involves
Options
A.insertion
B.Change in single base pair
C.duplication
D.deletion
Solution
The point mutation involves alterations in the structure of gene by alterations in the structure of DNA. point mutations are of two types(i) base pair substitution and (ii) frameshift substitution.
Insertion is the addition of one or more nitrogenous bases to a nucleotide chain.
Duplication is the presence of one block of genes more than once in a haploid component.
Deletion is the removal of one or more nitrognous bases from a nucleotide chain.
