Biology --- Protein synthesis

The central dogma

Brief outline

Protein synthesis takes place in all cells. Protein can come in many forms, such as enzymes, hormones and antibodies. It is a vital part of life.


The reason that protein synthesis is so vital to biology and the study of life is because without these proteins, normal function of cells would be compromised...and seeing as we're all made up of a bunch of cells...there's a serious problem if it doesn't go to plan!


Biology studies protein synthesis to better understand the way that we, and all living things, work.


What is protein synthesis?

Transcription and Translation

Transcription and translation are the stages of protein synthesis.


Starts with a DNA double helix in the nucleus, where a single strand is copied to an RNA strand. This strand is then modified slightly, and moves to a ribosome inside the cell. Once here, the genetic information is read by molecules called tRNA. Once the two connect, a portion of protein (called an amino acid) is produced. These link in chains and then fold to form a functional protein.
