Why is it essential for SARS-CoV2 RNA be translated on ribosomes before it can be replicated?

Biology
1 answer:
Natalka [10]3 years ago
5 0

The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.

What are some real life applications of using enumeration methods?
alina1380 [7]

Answer:

There are different methods of enumeration of bacteria like viable plate count, direct microscopic method, turbidity method, etc. These methods are used to find out the number and concentration of microorganisms in any sample.  

In real like the application of using enumeration methods can be seen in diary microbiology, food, microbiology, water microbiology, etc. In these sectors, the enumeration method is used to find out the quality of the food items, water.  

Water quality is checked by enumerating the number of coliform bacteria by serial dilution method. In food, bacteria that cause foodborne illnesses are enumerated by using the enumeration method.

Exercise and reactions to exciting stimuli include _______. A. increased activity in all parts of the peripheral nervous system
jok3333 [9.3K]

Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.

<h3>What is the sympathetic nervous system?</h3>

The autonomic nervous system includes the sympathetic nervous system. It might be referred to as the "automatic" nervous system because it controls many processes that we don't have to think about. This can affect a variety of bodily processes, such as the regulation of our heart rate, blood pressure, digestion, urination, and perspiration. For its role in reacting to risky or stressful conditions, the sympathetic nervous system is best known.

<h3>What is the parasympathetic nervous system ?</h3>

One of the two functionally separate and perpetually active divisions of the autonomic nervous system is the parasympathetic nervous system (PNS) (ANS). It opposes the sympathetic nervous system, which is the other (SNS). In calm "rest and digest" situations, the parasympathetic nervous system predominates, whereas the sympathetic nervous system activates the "fight or flight" response in stressful circumstances. The major functions of the PNS are to regulate body processes like digestion and urine as well as to store energy for later use.

Hence, Option B is correct.  Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.
