After replication, identical molecules of are produced

After replication, two identical molecules of DNA are produced

Explanation:

The replication of a DNA molecule results in two identical molecules. We can call the strands of the original DNA "parental strands" and the strands of the resulting molecules "daughter strands". Each of these daughter tapes is an almost identical copy of the parents (it is not always 100% due to possible mutations).

Parental tapes are used as a template or model. Each synthesized DNA strand (daughter strand) is made by adding a nucleotide that is complementary to the main DNA strand. In this way, DNA replication is semi-conservative, which means that the DNA molecule produced has a new thin (daughter) and an old (parental) strand.

the answer is b.) hydrogen bonds between bases.
