DNA replication occurs in the cell during cell division, during mitosis.
During the S-phase subphase of interphase during the cell
cycle.

Your Answer:How does the cell ensure that daughter cells receive exact copies of the
genetic information? 6/20/2020 Module 1 Problem Set: Essential Biology II with Lab- Correll

During this they pull the one copy of each chromosome with them to
opposite poles of the cell. Each daughter cell in turn will have 1 copy from
each parent of DNA. Complementary base pairs. The strands separate and act as a
template. This template ensures daughter cells will receive the
exact information.

Your Answer:What is the purpose of the origin of replication, and how many can be
found on a chromosome?
This is the point on DNA where replications tarts. With replication you can
get precise duplication of of copies of a portion of DNA. For chromosomes
of bacteria you can find one. For archaea it is three. Eukarya can have
many. Origins of replication encode a “start” signal to initiate
replication. There are many along the cell so that replication
can occur in many places and in both directions.
