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: The Cell Membrane
As we mentioned in an earlier blog post, a cell is essentially a drop of a thick, watery substance (cytoplasm) surrounded by a layer of fats (cell membrane). The cell membrane separates the inside of the cell from the outside…
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.…
