The DNA sequencing process makes it possible for researchers to discover the amino-acid

May 28, 2010
The DNA sequencing process makes it possible for researchers to discover the amino acid sequence in a substance. Shown here is Step 5 in the process: The end result. Once the gel plate has been moved to the DNA sequencer (see Step 4), the sequencer produces the images that allow researchers to see the nucleic acid sequence. Each color represents one of the four base chemicals that make up DNA: A (adenine), G (guanine), C (cytosine) and T (thymine). In this image, one of the lanes on the gel image is translated into a chromatogram (the lane on the far left). [Image 5 of 5 related images. See Image 1.]

More about this Image The work pictured in this series of images was performed at the DNA Sequencing Facility at Virginia Tech. Several of the researchers at the facility are National Science Foundation grantees. University facilities such as this one make it possible for students and faculty to perform hands-on research work, make discoveries and earn awards and grants. (Year of image: 2000)
