Retinoic acid (a metabolite of vitamin A) plays a key role in vertebrate development, differentiation, and organogenesis. Retinoic acid normally binds to the RAR receptor to initiate changes in gene expression. Researchers have determined that one type of RAR receptor is found at high levels in muscles, but is not found at all in neurons.

Retinoic acid (a derivative of vitamin A; Section 9-1F) is a hormone that mediates immune system function. Would retinoic acid require a receptor on the surface of a target

Question: What are three roles of retinoic acid in the developing embryo? defining the dorsal ventral differences in the heart, brain and limbs defining the differences between endoderm ectoderm and mesoderm defining the differences in the anterior-posterior axis of the heart, brain and neural crest.

Question: What happens to an animal raised on retinoic acid as its only source of vitamin A ?a. It becomes blind.b. Its growth is stunted.c. It produces more offspring.d. It cannot reproduce.e. It grows to an abnormally large size.

Retinoic Acid is a lipid-soluble molecule that crosses cell membranes and binds to intracellular receptors. Retinoic Acid alters gene expression in cells receiving the signal. Retinoic Acid signaling can only act in combination with Notch signaling, but BMP signaling can act independent of any other signal.

You are running an experiment in which you need to treat your cells with 10uM Retinoic Acid. You are given 10mL of cells for your experiment, and can only add 2uL of stock solution to your cells. What concentration should your stock solution be, so that you only have to add 2uL of reagent to your cells for a final concentration of 10uM Retinoic ...

Question: uring the patterning of the rostral neural tube in mice, high levels of Retinoic Acid will have the following effect: promote telenchephalon development. promote spinal cord development. Retinoic Acid does not play a role in rostral neural tube development. antagonize spinal cord development.
