Great job.
Question 5
How is it possible that each daughter cell during cell replication receives an
identical copy of the DNA?
Question options:
DNA is not identical in every cell, so all daughter cells have different copies
DNA is replicated following mitosis or meiosis, so is transferred after the new cells
DNA is replicated individually in each new cell after meiosis and mitosis
DNA is replicated during the synthesis phase of the cell cycle, prior to mitosis or m

Great job.
Question 6
Why does one strand of DNA replicate as a continuous strand, and the other
in fragments?
Question options:
they are parallel, and DNA polymerase can synthesize in either direction
