Question

Quizplus · Accepted Answer

Homeotic genes are responsible for controlling the development of the body plan, including the formation and positioning of body segments.

Answer: G
 Mutations in certain homeotic genes, such as BRCA1 and BRCA2, have been associated with an increased risk of breast cancer.

Answer: E
 Homeotic genes can also act as master regulators, inducing the expression of other genes that are necessary for the development of specific body structures or functions.

Answer: H
 Homeotic genes, like all genes, are regulated by binding sites on DNA where regulatory proteins can bind and increase or decrease transcription rates.

The other answer choices do not accurately describe homeotic genes.
