The answer is letter C.) <span>Affected father and carrier mother
"Affected" refers to the person having the recessive gene of the color blindness, while "carrier" means the person carries two of the recessive genes of the trait. For the couple to produce a 1:1 ratio of normal to color-blind offspring, they would need to have the combination of affected father and carrier mother.

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.
