RNA's Role in the Central Dogma

The central dogma of molecular biology explains that DNA codes for RNA, which codes for proteins. DNA is the molecule of heredity that passes from parents to offspring. It contains the instructions for building RNA and proteins, which make up the structure of the body and carry out most of its functions.

Inside the cells of all living things, tiny molecular machines are constantly reading the information in DNA and using it to build proteins. In exploring the activity below, you will learn about the three types of RNA are essential to this process: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
