Biotech Basics: 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…

Biotech Basics – Visualizing DNA

What is 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.…

Biotech Basics: Accuracy and Precision in Measurements (and a #SciArt Project!)

  What is the difference between accuracy and precision? Accuracy describes how close a measurement is to the true value of a given quantity.  Precision describes the reproducibility of the measurement. Accordingly, measurements can be categorized as follows: Neither accurate…

Biotech Basics: Agarose Gel Electrophoresis

Agarose gel electrophoresis is a biotechnology technique used to separate DNA molecules according to their size.  The mixture of molecules is added into depressions (or “wells”) within a gel, and then an electrical current is passed through the gel (Fig.…
