Concept explainers

Virus

Viruses are infectious microscopic agents that can only reproduce in live cells of animals, plants, or microbes and are smaller than bacteria. Vertebrates, invertebrates, plants, protists, and fungi are among their many hosts. Viruses are unable to multiply on their own due to the lack of necessary cellular machinery, but they can guide the cell machinery of a host to make additional viruses by infection. The virus enters and attaches to a particular host cell, injects its genetic material, and reproduces by using the host’s genetic material. Viruses cause infection by taking entry into the host cell and using the host cell’s enzymes and raw materials to multiply.

Question

What property of the retroviruses enables them to integrate into the
host genome?
a. the RNA they carry
b. presence of glycoprotein receptors
c. presence of reverse transcriptase
d. a positive-sense genome

Expert Solution

Step 1

The virus is the micro-organism that does not replicates independently and depends on host cells. It consists of a protein coat enclosing the nucleic acid that may be DNA or RNA. The virus follows the replicative cycle that includes the steps such as attachment, entry, integration, synthesis of viral components, assembly of virus and release of new virus.
