In molecular biology, complementarity describes a relationship between two structures each following the lock-and-key principle. In nature complementarity is the base principle of DNA replication and

Nucleotide excision repair
Videos
Nucleotide excision repair is a DNA repair mechanism. DNA damage occurs constantly because of chemicals, radiation and other mutagens. Three excision repair pathways exist to repair single stranded DN
Complementarity (molecular biology)
…damaged section and its replacement by using complementarity to copy information from the other strand, as occurs in the processes of mismatch repair, nucleotide excision repair and base excision repair. Nucleic acids strands may also form hybrids in which single stranded DNA may readily anneal with complementary DNA or RNA…
