The BiotechnologyEducation Company
BactoBeads™ are non-pathogenic, freeze-dried microbes (bacteria and lower eukaryotes) that are easily cultured for use in the classroom. Each bead contains microorganisms, buffer, salts and nutrient broth in an instantly soluble pellet.
DNA Ligase - Building a Bridge with DNA
DNA ligase is one of the most important, but least celebrated, enzymes used in modern biotechnology. This enzyme plays a very important role in DNA replication and repair by acting like a “glue” that can connect different DNA fragments to one another. Scientists take advantage of this molecular glue to combine DNA fragments to make an entirely new sequence. However, many people are merely using DNA ligase as a tool without knowing the story and mechanism behind it.

Visualizing DNA After Agarose Gel Electrophoresis
Electrophoresis is a technique that allows us to separate DNA, RNA or proteins into bands according to their size. For more information about this technique, be sure to check out our previous post describing electrophoresis.

Mutant Plants to the Rescue!
Bioremediation is a management tool that addresses environmental pollution. In bioremediation organisms remove or neutralize pollutants from a contaminated site. Often these organisms are already present at the site. For example a group of scientist from Rutgers University discovered a strain of bacteria that can breathe either oxygen or uranium in the soil of an old ore mill in Rifle Colorado.
