In Contrast to Bacteria, Eukaryotic Chromosomes Need Multiple DNA Replication

question 30

Multiple Choice

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

• A) eukaryotic chromosomes cannot usually replicate bidirectionally.
• B) eukaryotic genomes are not usually circular, like the bacterial chromosome is.
• C) the processivity of the eukaryotic DNA polymerase is much less than the bacterial enzyme.
• D) their replication rate is much slower, and it would take too long with only a single origin per chromosome.
• E) they have a variety of DNA polymerases for different purposes, and need a corresponding variety of replication origins.
