How does the base pairing rule affect DNA replication?

Base pair in DNA replication is a way that the chromosomes have to double check to make sure that the duplication is exact.

Base pair in is a way that the chromosomes have to double check to make sure that the duplication is exact.

The replication is termed semiconservative since each new cell contains one strand of original DNA and one newly synthesized strand of DNA. The original polynucleotide strand of DNA serves as a template to guide the synthesis of the new complementary polynucleotide of DNA. A template is a guide that may be used for example, by a carpenter to cut intricate designs in wood.
