WebGene mutations are the damage to the DNA that result in altered nucleotide sequence in the gene. As a result, the amino acid sequence in the proteins is altered and non-functional proteins are made. When a mutation occurs in a gene, the mRNA transcribed from this gene also have an altered nucleotide sequence. If a single base is altered, it is ...
