From Wikipedia, the free encyclopedia
dnaN is the gene that codes for the DNA clamp (also known as β sliding clamp) of DNA polymerase III in prokaryotes.[2][3] The β clamp physically locks Pol III onto a DNA strand during replication to help increase its processivity.[4] The eukaryotic equivalent to the β clamp is PCNA.
