DNA replication?

The RNA Pol produces only short RNA fragment called primer, which is essential for DNA Pol to start the polymerization, because it is not able to start de novo synthesis of DNA. DNA is only able to append nucleotides to some other chain. Thus the order would be 1) unwinding ...

Re: 3' to 5' Exonuclease question

... is my first time in this forum. As I read about DNA Polymerase III in "molecular biology of the cell" the enzyme has both functions of polymerization 5'-3' and exonuclease 3'-5'. They locate in two active site of this enzyme. When a nucleotide is mismatched at polymerase site, the enzyme ...

3' to 5' Exonuclease question

... notes of a molecular biology course recorded from Berkley (one of those free online courses where they record the classes) says that "Polymerization is a race between the 3' to 5' exonuclease and polymerase" (probably polymerase III). What does that mean? How can it be a race ...

Re: DNA and nucleotides

Thanks for the reply, Jack. Does the use of strictly dNTPs address energy issues during polymerization? Do diphosphates not provide enough energy for the reaction?

Proteins in Mitosos and the Cell Cycle :)

... then Cdh1 becomes phosphorylated by them and the Cdh1 then releases the APC/C, making it inactivated. As far as the proteins that influence the polymerization/depolymerization of tubulin for the spindle formations, they are called MAPs (Microtubule Associated Protein(s)). Dimers of alpha and ...
