Homeobox (HOX) genes play a role in controlling events of embryogenesis. These genes exert their functions through which of the following processes?
A) allelic exclusion
B) alternate mRNA splicing
C) regulation of transcription
D) regulation of translation
E) signal transduction

Question

Quizplus · Accepted Answer

Homeobox (HOX) genes are transcription factors that regulate the expression of other genes, thereby controlling the transcription process during embryogenesis. HOX genes are a group of related genes that control the body plan of the embryo. All of the proteins encoded by the HOX genes are transcription factors that contain a DNA-binding domain and function by binding to specific target genes and regulating their rate of transcription.
