<h3><em><u>C.</u></em><em><u> </u></em><em><u>This cell has no nucleus.</u></em></h3>
Because bacterial cell do not have a well-defined nuclear membrane. The coiled DNA particles lie naked in the cytoplasm. This is called nucleoid. While in animal cells the nucleus is surrounded by a well-defined nuclear membrane.

Answer:
<u>This is because the Viron has in its genome a specialized code for synthesising any missed enzyme for replication that is lacking in the host cell.</u>
<u>An example is the replication of the human DNA cells by the Immunodeficiency virus(HIV) </u>. Human cells only have enzymes for copying DNA templates, and lacks the enzyme to convert the HIV RNA genome to human DNA.However these viruses have in its genome; code for synthesising its own RNA polymerase enzymes that copies or transcribed the human DNA to HIV RNA.
<u>This ability of the viral cell to code for the host's enzyme has a therapeutic effect</u>. Drugs can be targeted at the viral polymerase enzymes to reduce the replication and therefore toxicity in the host cells.
