How is testing for brca1 or brca2 different from testing for a gene such as the tay-sachs gene? explain your answer in your labo
natka813 [3]

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.

How much has the greenhouse gas carbon dioxide increased in the air just in the last few years? ITS DUE IN A FEW HOURS PLEASE HE
ipn [44]

Answer:

approximately 2.3 parts per million (ppm) per year

Explanation:

In 2019, the global amount of atmospheric carbon dioxide (CO2) has been estimated at approximately 410 parts per million (ppm). These levels are higher than at any time in the last 800,000 years, and it has been estimated that in 2025 the CO2 levels will be higher than at any time in the last 3.3 million years. In 2018, there has been an increase of approx. 2.5 ppm, the same increase observed between 2017 and 2018. Moreover, the average increase of the CO2 levels in the atmosphere between 2009 and 2018 was 2.3 ppm each year.
