Genes to RNA to Proteins

Overview

Description

A key understanding in biology is that information in living things flows from genes to RNA to proteins. DNA is an important molecule found in all living things. Through a complex series of events, DNA controls the production of proteins that ultimately produce an organism's traits and allow the organism to function. Protein synthesis involves another molecule called RNA. RNA is responsible for taking the sequences encoded in DNA and making specific proteins. This progression from DNA that codes for RNA, which then makes proteins, is called the central dogma of biology. The function of proteins is dependent on the proteins' specific three-dimensional structure. There are several mechanisms that regulate which genes are active at any given time. This means an organism's protein profile can change as it moves through its life.
