of repliation origins per chromosome
In what end is the nucleotides attached during DNA replication? and what functional group is found
here? - ✔✔3' Hydroxyl Group
leading strand - ✔✔the new complementary DNA strand synthesized continuously along the
template strand toward the replication fork in the mandatory 5' to 3' direction
lagging strand - ✔✔A discontinuously synthesized DNA strand that elongates by means of
