Experiment that proved DNA was the genetic material
Hershey-Chase with T2

DNA Pol I has this nuclease activity
5' - 3' exonuclease: digests primers on lagging strand, and nick translation; 3' - 5' exonuclease: proofreading

DNA Pol II does this
"SOS" response, 3' - 5' exonuclease

Polymerization speed of DNA Pol III
9000/min

DNA Pol III has this nuclease activity
3' - 5' exonuclease: proofreading

Subunit of DNA Pol III, and it's special function
Beta subunit is sliding clamp

DNA Pol III does this
Primary enzyme for DNA replication, with proofreading.

DNA Pol I does this
DNA repair

Replisome
DNA Pol III (2 copies), helicase, primase.  Larger complex of enzymes at the replication fork.

Gyrase does this
Introduces supercoils, keeps DNA from tangling

Helicase does this
ATP driven unwinding of DNA

Helicase is also known as this
DNA B

How replication terminates in E. coli's chromosome
It terminates past 180 degrees of OriC, where palindromic Ter sequences have bound one-way valve proteins.

Replication of chromosome ends requires this
Telomerase, a ribozyme, which can deal with the portions vacated by the RNA primer.
