Partial Question 6 Which of the following are true about replisome components at the replication fork? There are two DNA helicases at each replication fork: one for the leading strand and one for the lagging strand. There are two sliding processivity clamps at each replication fork: one for the leading strand and one for the lagging strand. Primase synthesizes new primers made of DNA every ~500-5000 nt on the lagging strand. The clamp loader complex (y) loads new sliding processivity clamps (B) every ~500-5000 nt on the lagging strand. The two DNA polymerase cores travel together in the same direction even though the two template DNA strands run 5'→3' in the opposite direction (antiparallel).

Question 6
Which of the following are true about replisome
components at the replication fork?
There are two DNA helicases at each replication
fork: one for the leading strand and one for the
lagging strand.
There are two sliding processivity clamps at each
replication fork: one for the leading strand and one
for the lagging strand.
Primase synthesizes new primers made of DNA
every -500-5000 nt on the lagging strand.
The clamp loader complex (y) loads new sliding
processivity clamps (B) every ~500-5000 nt on the
lagging strand.
The two DNA polymerase cores travel together in
the same direction even though the two template
DNA strands run 5'→3' in the opposite direction
(antiparallel).
