Answer :
The premise of the Ames assay involves using a special strain of bacteria that lacks the ability to produce option C. an essential amino acid.
The Ames check detects whether a given chemical can reason a reversion mutation in his- microorganism.
Within mitochondria, cholesterol is transformed into pregnenolone by using an enzyme in the inner membrane referred to as CYP11A1. Pregnenolone itself isn't a hormone, however, is the instant precursor for the synthesis of all of the steroid hormones.
Whilst Ames check is used to identify the revert mutations which might be found in lines, it is able to also be used to hit upon the mutagenicity of environmental samples along with pills, dyes, reagents, cosmetics, wastewater, insecticides, and other materials that are easily solubilized in a liquid suspension.
