The correct answer is C) AUG AAU CCA UUU UGA.

Explanation:

First important thing to notice is that RNA doesn't have Thymine, all thymines are changed for Uracils. Then, the correspondency is thymine-Adenine, Guanine-Cytosine (and viceversa) Adenine-Uracil. Lastly, the transcription process happens from 3' to 5', so the question asks for the final result to be read to the opposite direction. Therefore, the correct answer is C.

The skin has only 2 layers—epidermis and dermis. Hypodermis, if that’s what you have in mind as the third, isn’t considered part of the skin.

The epidermis is a barrier to infection, trauma, and water loss (dehydration); it’s important to our social interactions; and it’s the body’s largest sense organ. The dermis provides toughness and resistance to mechanical stress; provides blood vessels that come close to the epidermis and nourish it (but don’t enter it); contains a variety of sensory receptors for touch, heat, cold, pressure, and vibration; and is an arena of immune defense in which white blood cells can rally at a site of infection and fight off intruders.
