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.…
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…
