Question

(b)

Describe how the antibody gene could be isolated from an animal cell and introduced into
a crop plant such as maize.

Answer 1

Firstly, we can use a DNA probe to identify the particular antibody gene that we are looking for.

We can cut the gene at specific restriction sites by using specific restriction enzymes.

The same restriction enzymes should be used to cut the DNA from the specific site in the maize plant.

The gene can be introduced and ligated in the maize genome by using DNA ligase.

The recombinant DNA can be places in the Maize cop plant.
