In this week's news, scientists announce that they’d made the first entirely computer-generated bacterial genome, and a new surgical procedure that does away with cuts and scars.

How to Read a Codon Chart

Explore the steps of transcription and translation in protein synthesis! This video explains several reasons why proteins are so important before explaining the roles of mRNA, rRNA, and tRNA in the steps of protein synthesis! Expand...

Join the Amoeba Sisters as they explain gene and chromosome mutations, and explore the significance of these changes. This updated video has improved audio and images! Codons and the amino acids they code for is represented by standard...

Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

Paul Andersen explains the central dogma of biology. He explains how genes in the DNA are converted to mRNA through the process of transcription. He then explains how ribosomes use this message to convert the mRNA to a functioning...

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

This video covers:

- The two steps of protein synthesis: transcription and transl
ation
- Transcription is the production of mRNA, which is a copy
of a gene
- Translation is the production of a sequence of amino...

This video covers:

- What genetic mutations
are
- What causes mutations e.g. carcinogens and harmful
radiation
- What the cons
equences can be
- The 3 types of mutations: substitution,

addition, deletion...

This video will explain and illustrate all steps of protein synthesis, starting with processing the RNA, followed by making a protein at the ribosomes (translation).

This video explores five fun facts about DNA.

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

Transfer RNA (tRNA), Codons, and Anticodons

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

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.
