Gene expression in developing organisms is regulated on several different levels.In many developing animals,regulation of gene expression is influenced by the action of Hox genes.Which of the following regulatory elements are produced by many Hox genes?
A)transcriptional factors
B)cell surface molecules for cell-cell interactions
C)signals from maternal cytoplasm,such as bicoid
D)mRNA processing factors

Question

Quizplus · Accepted Answer

Many Hox genes produce transcription factors that regulate the expression of downstream genes involved in developmental patterning. They do not produce cell surface molecules, signals from maternal cytoplasm, or mRNA processing factors.
