Just prior to mitosis, the DNA inside a cell is copied through a process called replication. During
replication, each strand of DNA acts as a template for the construction of a new, complementary
DNA strand.
After division, the resulting cells each contain one of the old strands, and a newly formed
complementary strand.
What is the purpose of this process?
A.
It ensures that the new cell has a complete, accurately sequenced set of
chromosomes.
В.
It increases the rate of cellular repair inside tissues.
C.
It rearranges the nucleotide sequences, so different types of tissues can be produced.
D.
It produces mutations that stop the expression of lethal recessive traits.
