Polymerase Switching in DNA Replication - ScienceDirect

Polymerases interact with the phosphate backbone and the minor groove of the DNA, so their interactions do not depend on the specific nucleotide sequence. The binding is largely mediated by electrostatic interactions between the DNA and the "thumb" and "palm" domains of the metaphorically hand-shaped DNA polymerase molecule. When the polymerase advances along the DNA sequence after adding a nucleotide, the interactions with the minor groove dissociate b… WebOn the processivity of polymerases. (Q40707346) From Wikidata.
