Explanation:
Many mRNAs have sequences of 50 - 150 nt rich in A and U in the 3' untranslated region. These sequences, called AU-rich elements, are important to regulate mRNA stability, because they bind proteins that target the mRNA for degradation.
When a protein binds to the AU-rich element of the mRNA, the polyA tail can be shortened and/or the 5'cap is removed, promoting mRNA degradation. In addition, the AU-rich elements in some mRNAs have been shown to inhibit protein translation.
The mRNA of the overexpressing cell line is about 200nt shorter than the normal cell line; this could mean that it has a deletion in the 3'UTR comprising an AU-rich element. If this is missing, the mRNA will have an extended half-life (because it won't be targeted for degradation) or it will be translated more. As a result, the protein expression will be increased.
Causes air pollution is the answer hope it helped
Answer:
Option C, ave destroyed much of the Arctic's fragile coastal ecosystem due to increased foraging.
Explanation:
Snow goose extensively involve in foraging activities in the small and concentrated areas. They spent large part of their day in foraging for instance female spends half of their day in foraging during spring and three fourth of their time before developing nest. Snow goose mainly feed on plants, underground roots and stems such as tubers, agricultural and aquatic plants. They destroy the habitat during winter foraging activities and make environment unsustainable
Hence, option C is correct
Answer:
Cell phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radiofrequency energy a person is exposed to depends on the frequency of the signal and the amount of time they spend on the phone. The Federal Communications Commission (FCC), the International Agency for Research on Cancer (IARC), and the American Cancer Society (ACS) all agree that more research is needed to determine the possible health effects of cell phone use. So far, there is no scientific evidence that proves that cell phone use causes cancer. Some studies have suggested a possible link between cell phone use and cancer, but more research is needed to confirm these results. The ACS does not recommend limiting cell phone use because the risk of cancer is still unknown.
Hope this helps!
