The best choice is D prokaryotes dont have a nucleus <span />
Answer:
A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.
Explanation:
Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.
The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.
If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.
<span><span>Mitosis is the process in which cells divide to
form new cells. The cell that is being described under the microscope is
already in the Anaphase stage in mitosis.
Anaphase is the process in which two sister chromatids separate and move to
opposite poles of the cell. These two sister chromatids contain identical
copies of DNA that are joined at the middle called centromere. The chromosomes
are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two
separate poles. The mitotic process then proceeds to the
Telophase.</span>
