Question

how do viruses aid genetic engineering?
○ they make the patient sick.
○ they deliver new dna to specific cells.
○ they create the mutations needed for gene editing.
○ they are molecular scissors used to chop dna in specific places.

Explanation:

Viruses can be engineered to carry new DNA. In genetic engineering, they act as vectors. Their natural ability to enter cells is exploited. They specifically deliver the new DNA to target cells. This helps in introducing desired genetic material for various genetic engineering applications like gene therapy.

Answer:

B. They deliver new DNA to specific cells.
