Q. 10 - Biology

Question

Which statement is true of viral replication? 

a. In the process of apoptosis, the cell survives. 

b. During attachment, the virus attaches at specific sites on the cell surface. 

c. The viral capsid helps the host cell produce more copies of the viral genome. 

d. mRNA works outside of the host cell to produce enzymes and proteins. 

Step-by-Step Solution

Answer

As the result, option $b$ is correct.

Step 1: Introduction

The process by which a cell dies is known as apoptosis. This is also referred to as "planned cell death." Necroptosis is the death of diseased or damaged cells.

Viruses are intracellular obligatory parasitic that do not live outside of their recipient or do live inside of it. They don't have any cells. They lack their own enzyme machinery therefore rely on the biochemical equipment of the host cell to multiply.

Within the host cell, mRNA (imessage rna molecule) generated by viral DNA (ribonucleic acid) transcription is interpreted to make enzymes and proteins. The infectious capsid offers no assistance to the human host in the replication of the viral DNA.

Step 2: Explanation

As a result, choices $a$, $c$ and $d$ are erroneous.

Attachment proteins are found in the viral envelope, and gene products are detected in the viral particle. These attachment proteins and glycoproteins assist the virus connect to the host cell by recognising specific receptor sites on the host cell's cell membrane.

Step 3: Conclusion

Option $b$ is the best answer.
