DNA polymerase Families, Error rates and Functions

DNA polymerase Families, Error rates and
Functions
A, B, C and X families of DNA polymerases are
stalled by DNA lesions, such as 1) pyrimidine
dimer, 2) polycyclic aromatic DNA adducts and 3)
abasic sites. Only Y family of DNA polymerases
are able to efficiently perform translesion DNA
synthesis.
