A) a cis regulatory element
B) a trans regulatory element
C) a transcription factor
D) a homeobox

Question

Quizplus · Accepted Answer

Cis regulatory elements are noncoding stretches of DNA that control the spatial and temporal expression of nearby genes on the same strand. Trans regulatory elements act on genes located on different strands or at distant locations in the genome. Transcription factors are proteins that bind to DNA to help regulate gene expression. Homeobox genes are a family of genes involved in the regulation of embryonic development.
