Using the theories of mutation, we got that the effect of a nucleotide-pair substitution that results in a nonsense mutation in a gene is -
A nonsense mutation is the substitution of the single base pair that leads to the appearance of the stop codon where previously there was a codon specifying an amino acid.
A substitution mutation is when one nucleotide is actually swapped out for another. These types of the mutations are the least dangerous of all the DNA mutations.
Hence, the effect of a nucleotide-pair substitution that results in a nonsense mutation in a gene is that -It introduces a premature stop codon into the mRNA.
