It is possible to use molecular genetic techniques to characterize the T cells found in psoriasis plaques and compare them to the T cells found in healthy skin. In healthy skin, T cells have a wide diversity of T cell receptors. In other words, there are many different T cell clones found in healthy tissue. In psoriasis plaques, there are fewer T cell clones, but often there are a large number of T cells representing only a small number of clones (this is called oligoclonal expansion). There are usually many more T cells in total found in psoriasis plaques relative to healthy skin. Think about the implications of this finding. What conclusion is NOT supported by these findings?

a. specific T cells react with many different antigens in psoriasis
b. specific T cells react with skin antigens in psoriasis
c. specific T cells have expanded in psoriasis lesions incorrect
d. specific T cells have homed to psoriasis lesions

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
