Question

manipulate dna and cause mutations. an example of a biological agent is the influenza virus that causes the flu. what is a transposon? a jumping gene that can move dna around a synthetic chemical that can cause mutations a type of harmful radiation

Explanation:

Transposons are segments of DNA that have the ability to move (transpose) around within the genome of a single cell. They are often referred to as "jumping genes". The option "a synthetic chemical that can cause mutations" describes a chemical mutagen, not a transposon. The option "a type of harmful radiation" describes a physical mutagen (like UV rays, X - rays), not a transposon.

Answer:

a jumping gene that can move DNA around
