check all that apply
□ they can move within a chromosome.
□ they can move between chromosomes.
□ they are protein segments.
□ they influence phenotype.

Explanation:

Transposons (jumping genes) are DNA segments that can move (transpose) within a chromosome or between chromosomes. Their movement can disrupt genes or regulate gene expression, thus influencing phenotype. They are DNA, not protein segments. So the true statements are the first, second, and fourth.

Answer:

A. They can move within a chromosome.
B. They can move between chromosomes.
D. They influence phenotype.
