If the nucleosome core occupies 147 bp of DNA and the organism has a linker DNA length of 60 bp, then what is the maximal number of nucleosomes that can occupy a 2412 bp segment of DNA? Your answer must be a whole number.

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.
