DNA transcription (basic detail)

This animation shows that the first phase of the process of reading DNA information to make proteins starts with a molecule unzipping the DNA. The molecule then copies one of the strands of DNA into a strand of RNA, a close cousin of DNA. This process is called transcription.

Translation (basic detail)

This animation shows that the ribosome is a molecular factory that translates the genetic information in RNA into a string of amino acids that becomes a protein. Inside the ribosome, the genetic code of the RNA is read three letters at a time and compared with the corresponding code on a transfer molecule. When a...

Translation (advanced detail)

In this animation, messenger RNA (mRNA) carries DNA's genetic information to the ribosome, where it is translated into a sequence of amino acids. mRNA is fed into the ribosome, and it is positioned so that it can be read in groups of three letters, known as codons. Each mRNA codon is matched against the transfer...

DNA replication (advanced detail)

This animation shows how both strands of the DNA double helix act as templates for the new DNA strands. Incoming DNA is unraveled by the enzyme helicase, resulting in the 3' strand and the 5' strand. The 3' strands and the 5' strands are replicated by a DNA polymerase enzyme but in different ways.

Zoom in on your genome

This video shows the various levels of DNA packaging and the four basic building blocks of DNA. it allows you to take a journey into the body to see where the genome is found and how DNA is packaged in the nucleus of the cell. The journey starts outside the body and takes you into the liver and a liver cell. You...

DNA replication (schematic)

An animation showing that the structure of DNA, discovered by James Watson and Francis Crick, suggests a mechanism of DNA replication. The double helix unwinds, and each strand acts as a template for the construction of the new DNA molecule.

DNA replication (basic detail)

Using information from molecular research, this 3-D animation shows how DNA is replicated at the molecular level. It involves an enzyme that unwinds the DNA, and other enzymes that copy the two resulting strands.
