Explanation:
The correct answer is providing structure, regulating cell processes and creating movement
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.
The best way to determine the presence of halogens is by adding a silver nitrate solution to the solvent. This is because all halogens, except for fluorine, produce a precipitate with silver nitrate solution.Chlorine produces a white precipitate, bromine produces a pale cream colored precipitate and iodine produces a yellow colored precipitate.
If further testing is required, concentrated sulfuric acid may be added. The sulfuric acid will produce misty fumes with fluorine and chlorine, brown fumes with bromine and purple fumes with iodine.
hope this helped :)
