What information could cancer researchers gain from using DNA microarrays?

Biology
1 answer:
Evgen [1.6K]3 years ago
7 0

DNA microarrays allow scientists to determine the genotype of a chunk of our genome and also measure the how the genes in that chunk are expressed. Using this technique has been essential in isolating genes that predispose people to cancers, and therefore allowing physicians to preemptively identify and monitor at-risk individuals. For instance, the genes BRCA1, BRCA2, and PALB2 have all been identified (using DNA microarrays) and linked to breast cancer. Knowing this allows individuals to seek out testing and take appropriate measures to prevent cancer/monitor the possible onset of cancer, which has proven to be life-saving.

Enzyme Activity and pH
sveticcg [70]

Explanation:

B) After determining the optimum pH, they could vary the temperature of the environment to see if catalase is temperature specific

Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme catalase facilitates the breakdown of hydrogen peroxide into oxygen and hydrogen. Catalase specificity is affected by pH, temperature and the presence of inhibitors.

In temperatures beyond its optimal range, catalase may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. H2O2 would no longer be able to bind to the active site, and thus would not be broken down.

Mammals have two traits that set them apart from all other animal.
Sav [38]

One thing that separates us from the other animal classifications is that we have hair, everywhere! :D The next major difference is the fact that mammals don't lay egg's, we give birth to live creatures. Those are the 2 biggest things that distinguish us from them.

Hope I helped. :)
