Question

Papillomavirus genome is replicated in _____________ of infected cells, and virons are assembled in ___________.

A. nucleus, nucleus

B. nucleus, cytoplasm

C. cytoplasm, nucleus

D. Cytoplasm, cytoplasm

Answer 1

The answer is A) nucleus, nucleus.

HPV infection is caused by the human papilloma virus .

Human papilloma virus has dna virus, it is transmitted sexually and it infects the genital organs.

It is the most commonly sexually transmitted disease.

It's symptoms includes warts.

Generally the virus cannot replicate on its own, they replicate in the infected cell.

Firstly, the virus enters the infected cell, then early viral genes are expressed which helps the viral cells to enter into the 's' phase of the cellcycle. Finally the viral dna gets replicated.

This occurs in the nucleus of the infected cells.

Later thousands of viral genomes are produced from the nucleus of the infected cells.

Virions are nothing but virus, that means it includes the protein component and nucleic acid component.

Generally virions are assembled in cellular compartment where replication of genome takes place.

Rna viruses assemble in cytoplasm and dna virus assemble in nucleus.

And these virions are released during lysis of the infected cells.

Since human papilloma virus is a dna virus, so, the virions are assembled in nucleus of the infected cells.
