The Information in DNA Is Decoded by Transcription
Thus, the elongation period of transcription creates a new mRNA molecule from a single template strand of DNA. As the mRNA elongates, it peels away from the template as it grows (Figure 5).

The Nuts and Bolts of DNA Replication:
After each of the old strands is copied in this way, there are two new double-helix molecules, each one containing one strand it inherited from the original molecule and one newly-formed strand.

DNA: The Blueprint of Life
This process is essential for the proper functioning and survival of all living organisms. DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division.
