Question

In the production of transgenic animals, what is the correct sequence of the first three steps?

Options

• Attach the gene to a vector, identify the gene of interest, isolate the desired gene

• Introduce the gene into an embryo, identify the gene of interest, isolate and attach the gene

• Isolate the desired gene, introduce it into an embryo, attach it to a vector

• Identify the useful gene of interest, isolate the desired gene, attach the gene to a suitable vector or prepare it for transfer

Answer 1

The production of transgenic animals follows a logical sequence: first, scientists must identify which gene is useful for the desired outcome. Second, the identified gene must be isolated from the source organism. Third, the isolated gene must be attached to a suitable vector or prepared for transfer into the host. This sequence ensures proper planning, identification, and preparation before introducing the gene into living cells.
