Why Are Proteases Added While Isolating the Dna?

During isolation of the DNA, it is treated with proteases (enzymes which degrade proteins) to remove any such proteins which may interfere with the genetic engineering processes.

Why is protease added in DNA extraction?

Proteases catalyze the breakdown of contaminating proteins present in the solution to its component amino acids. It also degrades any nucleases and/or enzymes that may be present in the sample. This is of vital importance since these chemical compounds can attack and destroy the nucleic acids in your sample.

What is the purpose of a protease?

The function of proteases is to catalyze the hydrolysis of proteins, which has been exploited for the production of high-value protein hydrolysates from different sources of proteins such as casein, whey, soy protein and fish meat.
