The BRCA 1 and BRCA 2 genes are two genes that are sought in the genetic study of an individual in order to seek a predisposition to breast cancer (in women and also in men).
The genes of Tay-sachs, are researched in order to diagnose or eliminate Tay-sachs disease.
The first difference lies in the goal of the research: for the BRCA (screening) genes, a predisposition is sought and for the Tay-sachs genes, it is sought to confirm the disease.
The second lies in the technique used:
The first step in the study of these genes is to isolate and replicate them. The best technique for this is the PCR (polymerase chain reaction). By using primers we can amplify the gene we want. So the primers used in BRCA and Tay-Sachs research are necessarily different.

I believe it's the last question, How much water does it take to make a plastic bag?.
<span>The answer is A. pharynx. The pharynx is a cavity behind the nose and mouth which serves as a passageway for both air and food. The passage for air begins at the nose and nasal cavity while the passage for food begins at the mouth and mouth cavity. These two passages cross at the pharynx but separate soon after. Air passes through the larynx and later into the trachea and bronchus on its way to the lungs. Food passes through the esophagus on its way to the stomach.</span>
