Multiple Choice

Which of the following is a characteristic of Hox genes?

They function exclusively in the process of DNA replication.

They are only found in prokaryotic organisms.

They encode transcription factors that regulate the development of body plans along the anterior-posterior axis.

They are responsible for the synthesis of ribosomal RNA.

Verified step by step guidance

Understand what Hox genes are: Hox genes are a group of related genes that control the body plan of an embryo along the head-tail (anterior-posterior) axis.

Recall the function of Hox genes: They encode transcription factors, which are proteins that bind to DNA and regulate the expression of other genes during development.

Recognize that Hox genes are not involved in DNA replication or ribosomal RNA synthesis, which are different cellular processes.

Note that Hox genes are found in multicellular eukaryotic organisms, not prokaryotes, as they play a role in complex body plan development.

Conclude that the key characteristic of Hox genes is their role in regulating developmental processes by encoding transcription factors that determine body plan along the anterior-posterior axis.
