Quiz 4: DNAReplication_Set2

The role of the Dam methylase is to:

modify the template strand for recognition by repair systems.

Which statement is FALSE regarding the DNA ligase mechanism?

One of the products of the reaction is ADP.

At replication forks in E. coli:

RNA primers are synthesized by primase.

Which statement is FALSE regarding DnaA?

DnaA is a sequence that is part of oriC in E. coli.

An Okazaki fragment is a:

segment of DNA that is an intermediate in the synthesis of the lagging strand.

E. coli DNA polymerase III:

is the principal DNA polymerase in chromosomal DNA replication.

Which factor is NOT required for elongation during DNA replication in E. coli?

DnaC

Which phrase describes a role for E. coli DNA Pol III?

both lagging strand synthesis and mismatch repair

In contrast to bacteria, eukaryotic chromosomes need multiple DNA replication origins because:

their replication rate is much slower, and it would take too long with only a single origin per chromosome.

DNA replication in E. coli:

requires DNA-dependent RNA synthesis.
