Describe the specific problem that might arise during DNA replication of bacteria if the protein listed were absent or nonfunctional. I am looking for a description of how DNA replication will be impacted â not simply that the bacteria will die â which it well (listed in alphabetical order):
a.DNA ligase |
b.DNA pol III |
c.DNA polymerase I |
d.DNAa |
e.Helicase |
f.Primase |
g.Sliding clamp |
h.Topoisomerase/DNA gyrase |
What are the major differences between eukaryotic and bacterial DNA replication? Choose items below that are found in eukaryotic DNA replication.
DNA is wrapped around histones | ||
DNA is circular | ||
helicase separates the two strands of DNA | ||
gyrase releives torsional stress | ||
DNA is linear | ||
the ends of chromosomes shorten with each cell division in most cells | ||
DNA replication is terminated by the Tus/Ter complex | ||
DNA replication is terminated when replication bubbles meet | ||
DNA polymerase III replicates both leading and lagging strands of DNA | ||
DNA replication is initiated when Iniator proteins bind to the origin of replication | ||
licensing factors ensure that each origin of replication is used only once |
