Question

Forms a provirus. Virus attaches to the host using specific receptors on the cell membrane. Viral DNA integrates with the host cell DNA forming a provirus.Can remain dormant for months or years, spreading the infection to daughter cells during mitosis.

Answer 1

Answer:

This process is called as the malignant transformation, which is described as below;

Malignant transformation:The DNA of which (pro-virus) is integrated into the chromosomal DNA of the host cell. As the pro-virus may lay dormant for a  much longer duration, and can hide it self by suppressing its genes. Now as they grow in number, they are able to infect other organs as well because there DNA is also replicating along with the host cell.

In general, cells with integrated pro-viral DNA are converted into cancer cells.

Explanation:

• The host cell always undergo the process of mitosis and following the mitosis of the transformed cell, each new cell receives a copy of the pro-viral DNA.

• The hallmark of these transformed animal cells is that their growth is uncontrollable. Unlike normal cells, their growth is not inhibited by contact with other cells, and they lose their capacity to adhere (anchor) to certain surfaces.

• Which eventually show up as cancer in that part of the body. And then they are treated as per the conditions and the scenario of the body.
