18. As a result of DNA
replication two DNA molecules
come into existence. Why isit
not correct to assert that two
“new” DNA molecules are
created? What is the name
given to the process
concerning that fact?

During replication each chain of the DNA
acts by pairing new
nucleotides and after the process
newly formed chains made with the
union of these nucleotides appear. Then
two DNA molecules are created, each
with chain from the original
molecule and new chain formed by
new . Thus it is not entirely
correct to assert that the replication
produces two new of DNA. It
is better to affirm that two new half molecules
are created.

For this phenomenon DNA replication is
called semiconservative .
