steps in DNA replication 1

Question 1

DNA synthesis begins at the

Answer 1

origin of replication (modeled as oriC) in prokaryotes

Question 2

formation of a replication fork must occur:

Answer 2

zone of unwound DNA where DNA polymerization is occuring

Question 3

1. DNA topoisomerases, like DNA gyrase, remove the

Answer 3

supercoils in the DNA to create linear DNA

Question 4

2. DNA is nicked

Answer 4

DnaA proteins bind to the origin and cleave the hydrogen bonds between complementary strands

Question 5

3. Next DNA helicase acts to unwind

Answer 5

the DNA for a short distance and expose it as two single-stranded regions
