Question

1. which of these is an example of genetic modification?

2 pts.
a. mapping the genome of a giant squid
b. comparing the genes of children to their parents
c. learning about your ancestry from a dna sample
d. adding a gene for mold resistance to corn dna

Explanation:

Genetic modification involves intentionally altering an organism's genetic material by adding, removing, or changing genes. Option A is genome mapping (a sequencing/analysis task, not modification). Option B is genetic comparison (analysis of existing genes). Option C is ancestry testing (analyzing existing DNA). Only Option D describes inserting a new gene into an organism's DNA, which is genetic modification.

Answer:

D. Adding a gene for mold resistance to corn DNA
