The complementary nature of base pairing allows for the accurate replication of DNA during cell division and the transcription of DNA into RNA for protein synthesis.

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).
