Question

Why can genes be successfully shared and expressed across all living species in genetic engineering?

Options

• All living species produce human insulin in cow's milk.

• The fundamental genetic code is similar across all living species.

• All living species contain the β-galactosidase promoter region.

• All living species contain the luciferase gene from a firefly.

Answer 1

Genetic engineering is highly effective because the fundamental genetic code is similar across all living species. This similarity allows genes to be successfully shared and expressed.
