Question

Write a 250-word paragraph about the structure and function of this virus. This paragraph should address the following questions:

1. What kinds of genomes can viruses have?

2. What kind of genetics does SARSCOV2 SPECIFICALLY have?

3. How does this determine the life cycle of the virus? For example, what would be different about an RNA virus or a negative sense virus? 4. How many proteins does it code for?

5. What do those proteins Do in general terms?

6. Is this virus enveloped , or not? What does that mean?

Answer 1

Virus are small microscopic organisms that are non-functional outside. They are functonal and multiply only when present inside a host organisms. They are very small with size ranging from 35- 50 nm in size whereas recent SARS COV-19 is reported to be very lager than the average virus size i.e. approx 50-200 nm.

Viruses are unicellular organisms that lack cell wall instead they have a thick protein coat. Inside the protein genetic material is present. Depending on the type of genetic material they can be classifies ad DNA or RNA virus.

SARSCOV2 is an RNA virus that upon entering the host cell injects its RNA inside the host cell. It then multiply using reverse transcriptase where the DNA is synthesized from the virus mRNA. Then it use the host machinery to produce ther necessary protein and other molelules to reproduce.

SARSCOV2 is an negative sense RNA virus that use the antisense mRNA as its genetic material to multiply inside ther host. RNA virus use its RNA as the gentic material.

Viral protein can be classified on the basis of their function once produced synthesized using the host machinery. Structural perotein as the coat, enzymes, regulatoey and accessory proteins.

SARSCOV2 is coated with thick protein coat. It helps the virus to produce the enzymes necessary to dissolve the host cell wall to inject its genetic material and to assemble the Ribosomal complex to produce thw viral enzymes for multiplication.
