Vedclass · Answer

(C) Mutations are changes in the genetic material of an organism. $1$. Base pair substitution: This involves the replacement of one nucleotide base with another,which can lead to a change in a single amino acid (missense mutation) or a stop codon (nonsense mutation). $2$. Frame-shift mutation: This occurs due to the insertion or deletion of one or more nucleotide bases,which shifts the reading frame of the genetic code,often resulting in a completely different protein sequence. Both of these processes alter the nucleotide sequence within a gene. Therefore,both are types of mutations that affect the gene sequence.

Mutations that alter the sequence of nucleotides within a gene are known as:
