DNA

Genes code for proteins. In this lecture (part 2 of 2), you will learn how DNA codes for mRNA (transcription), and how mRNA codes for a protein (translation).

DNA is the code of life, and all life requires replication. This lecture will introduce you into the process by which DNA makes copies of itself and how it repairs mistakes.

This is an introduction to the chemical structure and function of nucleic acids, DNA and RNA.

Genes determine proteins. This is the first of two lectures that describes how DNA codes for proteins.

Meiosis is the production of gametes, sex cells. In meiosis, the DNA is split in half. This is important because fertilization combines the gametes of different organisms, and if meiosis didn't occur, the amount of DNA in a cell would quickly become too abundant to allow for efficient handling of cell function.
