DNA REPLICATIONCarolina Zapata Ramrez
Ribonucleotide reductase (RNR) catalyzes the reduction of ribonucleotides to the corresponding deoxyribonucleotides, which are used as building blocks for DNA replication and repair. This process is tightly regulated via two allosteric sites, the specificity site (s-site) and the overall activity site (a-site).
Enzyme that Maintains DNA Building Blocks
Newswise STONY BROOK, NY, February 10, 2016 A team of scientists led by Stony Brook University biochemist Huilin Li, PhD,
DNA is unwound by a type of pump jack mechanism, similar to the way one operates on an oil rig.
