Gene Activity

The central dogma of molecular biology explains how the information, or message, contained in a gene produces a protein. The diagram shows that two steps are involved. In the first step, called transcription, the DNA serves as a template to make an RNA molecule which is a copy of the message. In the second step, called translation, the RNA message is translated into protein language. This directs the construction of a protein with a particular sequence of amino acids.
