Incorrect.

Question

Leading and lagging strands occur in DNA replication because:

the parent DNA strands are complementary.

DNA polymerase can add nucleotides to both ends of a new strand of DNA.

DNA polymerase can only add nucleotides to the 3’ end of a growing strand of DNA.

the parent DNA strands are the template for the daughter strands.

of the base pairing rules.

Correct.

Question

The origin (Ori C) is:

a replication enzyme.

where protein coding genes start.

a sequence of DNA where genes are turned into proteins.

a sequence of DNA where DNA replication is initiated.

where the DNA molecule starts.

Correct.

Incorrect.

Question

DNA polymerase III begins synthesizing DNA from where?

from the 3’-hydroxyl at the end of an RNA primer

from random points along the template DNA strands

from the origin of replication (Ori C)

from the 5’-phosphate at the end of an RNA primer

from the point if attachment of DNA helicase

Correct.
