What is the unique site on chromosomal DNA where replcation begins? | origin of replication (ORI) |
What is the ORI of E. coli ? | oriC |
What is the enzyme that unwinds a DNA or RNA double helix? | helicase |
What is the fragment of E. coli DNA polymerase I that lacks the 5' to 3' exonuclease activity of the parent enzyme? | Klenow fragment |
What is the strand that is made discontinuously in DNA replication? | lagging strand |
What is the strand that is made of continuously in DNA replication? | leading strand |
What is the enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond? | ligase |
