Question

Quizplus · Accepted Answer

A homeobox is a specific DNA sequence that encodes a domain called a homeodomain. This domain is found in many transcription factors and is responsible for binding to DNA and regulating gene expression. Therefore, while a homeodomain is a protein sequence, a homeobox itself is a DNA sequence. Additionally, homeoboxes are present in both plants and animals.
