The resulting organism, called a mutant, may have a recognizable change in phenotype compared to the wild type, which is the phenotype most commonly observed in nature. A change in the DNA sequence is conferred to mRNA through transcription, and may lead to an altered amino acid sequence in a protein on translation.

Missense mutation: This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene (Figure \PageIndex1).

Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. Repair mechanisms correct the mistakes. In rare cases, mistakes are not corrected, leading to mutations; in other cases, repair enzymes are themselves mutated or defective.

It covers types and causes of DNA mutations, mechanisms of DNA damage, and major DNA repair pathways, including base excision repair, nucleotide excision repair, mismatch repair, and double-strand break repair. The text also discusses the biological consequences of mutations and the importance of DNA repair in preventing diseases like cancer.
