The phosphodiester bonds that link adjacent nucleotides in both rna and dna:

a) always link a with t and g with c.
b) are susceptible to alkaline hydrolysis.
c) are uncharged at neutral ph.
d) form between the planar rings of adjacent bases.
e) join the 3' hydroxyl of one nucleotide to the 5' hydroxyl of the next.

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.
