DNA codes for proteins

Discover how a cell translates the DNA code into proteins. This is done through a messenger called ribonucleic acid (RNA), which is like the recipe from a single gene for assembling a protein. Watch animations to see how different enzymes unzip the DNA double helix, read the code, and translate into protein. Find out how ...


Loading an agarose gel for gene sequencing

This is a close-up colour photograph of an agarose gel immersed in a clear liquid, a buffer solution. A purple solution containing DNA and a dye is being loaded into a well within the gel. The end of the pipette used to transfer the purple solution is shown, and air bubbles can be seen throughout the gel. The image is pale ...


UV light reveals DNA fragments

This is a colour photograph of an agarose gel in a plastic gel tray on an ultraviolet (UV) transilluminator, or light box. The gel contains DNA fragments that have been dyed with ethidium bromide (EtBr), causing the DNA to fluoresce a reddish-orange colour (seen here as pink lines) when exposed to UV light. This gel is ...


Using a multichannel pipette in mapping the rice genome

This is a colour photograph of a laboratory instrument called a multichannel pipette being used by a scientist in a biotechnology laboratory of the International Rice Research Institute (IRRI) in the Philippines. The pipette tips are being loaded with a solution containing a blue dye and probably DNA. This instrument is ...


DNA identification of tsunami victims

This is a colour photograph of a scientist in a laboratory holding a computer-generated chart of DNA information, called an electropherogram. The electropherogram displays DNA information of victims of the Indian Ocean tsunami of 2004. The chart has three rows of data with distinct linear peaks.


DNA sequencing gels for genetic and medical research, close-up

This is a close-up colour photograph showing the results of four DNA sequencing gels, each representing a separate DNA fragment. For each of the DNA fragments, a set of four dark banding patterns is shown. There are some reddish-pink pen markings identifying some bands.
