Genetic Expression Set: 6. This clip provides a detailed look at the translation of M RNA into protein.

In this video, we are going to discuss the structure and uses of protein molecules. Proteins are long-chain molecules made of strings of amino acids joined together. All amino acids are compounds with a similar basic structure: they have...

The video is about the structure of DNA. It explains that DNA is a polymer made up of repeating nucleotide units consisting of a sugar, phosphate, and base. The video also discusses base pairing, in which complementary strands of DNA...

DNA (deoxyribonucleic acid) is a molecule that is often called the blueprint of life. Located in the nucleus, the DNA is a very long molecule with a helix winding structure like a twisted ladder. The rungs of the ladder are made of four...

Proteins are made of a long chain of amino acids, which has been coded for by DNA. The order of the bases of DNA determines which protein is made, by coding for a specific order of amino acids. This is protein synthesis, and in this...

Genetic Expression Set: 1. This clip introduces the process of gene expression, whereby information stored in the DNA of a gene is transcribed into messenger RNA and translated into a protein gene product.

Cell Structure and Function Set: 10. This clip looks at the structure of ribosomes and examines how they facilitate protein synthesis during the translation of M-RNA.
