Answer:
The correct answer is a) The cell underwent repeated mitosis, but cytokinesis did not occur.
Explanation:
Multinucleated cells go through mitosis and form many nuclei but as there's no cytokinesis involved, therefore, the cell never actually separates. This type of cells, that are formed with a process of the mitosis without cytokinesis is called coenocyte.
Answer:
D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.
Explanation:
Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.
After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.
