[Campbell Biology P.515] Which statement accurately describes homeotic genes? | Practice Question
Which statement accurately describes homeotic genes?
A: They encode transcription factors that regulate the expression of genes responsible for specific anatomical structures.
B: They are found exclusively in Drosophila and other arthropods.
C: They are the only genes that contain the homeobox domain.
D: They encode proteins that form anatomical structures in the fly.
Explanation
Homeotic genes encode transcription factors, which are proteins that bind to DNA and control the transcription of other genes. These genes are crucial for specifying the identity of body segments or structures during embryonic development.
