Introduction. This lab will determine the presence or absence of amplified DNA in your samples by visualization on an agarose gel. Arthropod and Wolbachia DNA, if present, will be distinguishable based on the size, or base pair (bp) length, of the DNA molecule.
Sort and measure DNA strands by running your own gel electrophoresis experiment.
Virtual Labs. Gel Electrophoresis. Have you ever wondered how scientists work with tiny molecules that they can't see? Here's your chance to try it yourself! Sort and measure DNA strands by running your own gel electrophoresis experiment. See how gel electrophoresis is used in forensics. Can DNA Demand a Verdict? Try it Yourself.
Protein gel electrophoresis is a laboratory technique that separates proteins by mass. This technique is similar to running an agarose gel to separate and visualize different molecules of DNA.
New York Stories: Restriction Enzyme Analysis. In the early days of DNA manipulation, DNA fragments were laboriously separated by gravity. In the 1970s, the powerful tool of DNA gel electrophoresis was developed. This process uses electricity to separate DNA fragments by size as they migrate through a gel matrix.
We believe interactive simulation and visualization tools can help. We created Gelbox, a dynamic “scientific sandbox” that can aid in visualizing various ways that gel bands, sample molecules, and the gel itself, interact.
In this lab, we saw how gel electrophoresis could be used to determine the molecular composition and the specific charge. We were able to use gel electrophoresis successfully to determine how many different DNA, RNA, or proteins are present in a sample and how large they are in comparison to one another.
