We now consider in more detail the repair processes that rescue damaged DNA. DNA is not nearly as robust as popular media makes it out to be.

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.

As you already know, even minor changes in DNA sequence, such as point mutations can sometimes have far-reaching consequences. Likewise, unrepaired damage caused by radiation, environmental chemicals or even normal cellular chemistry can interfere with the accurate transmission of information in DNA.

This page outlines how DNA mutations can affect the polypeptide's sequence. Topics include what a mutation is, how mutations can be produced through exposure to mutagens, and how mutagens are classified. Small-scale and large-scale mutations are introduced. Finally, the basic mechanisms for DNA repair of these mutations is explored.
