How brief is brief?

Transcription is the synthesis of RNA from a DNA template.

Only one strand of DNA is copied.

A single gene may be transcribed thousands of times.

After transcription, the DNA strands rejoin.

Some of the RNA produced by transcription is not used for protein synthesis. These RNA molecules have other functions in the cell.

Translation is the process where ribosomes synthesize proteins using the mature mRNA transcript produced during transcription.

The diagram below shows a ribosome attach to mRNA, and then move along the mRNA adding amino acids to the growing polypeptide chain.
