Which of the following would NOT be true of cDNA produced using human brain tissue as the starting material? Which of the following would NOT be true of cDNA produced using human brain tissue as the starting material? It could be labeled and used as a probe to detect genes expressed in the brain. It lacks the introns of the pre-mRNA. It could be amplified by the polymerase chain reaction. It was produced from pre-mRNA using reverse transcriptase.

Imagine a self-reactive t cell that has not undergone clonal deletion in the thymus (that is to say, it has escaped central tolerance). if it encounters self antigen in the absence of an infection or inflammation, what will happen to this self-reactive t cell? (select two answers) (a) the t cell undergoes clonal expansion. (b) the t cell gains effector functions. (c) the t cell undergoes apoptosis. (d) the t cell becomes activated. (e) the t cell becomes anergic.
