DNA Replication Fork: Template DNA is read from the 3' to 5' direction
• primase: adds RNA primers to start DNA replication
• DNA ligase: combines Okazaki fragments together
A new DNA strand elongates only in the 5 to 3' direction because
A) DNA polymerase begins adding nucleotides at the 5' end of the template.
B) Okazaki fragments prevent elongation in the 3' to 5' direction.
C) replication must progress toward the replication fork.
D) DNA polymerase can only add nucleotides to the free 3' end.
