Atypical prokaryotic cell has about 3,000 genes in its dna, while a human cell has about 20,500 genes. about 1000 of these genes are present in both types of cells.
a) based on your understanding of evolution, explain how such different organisms could have this same subset of genes.

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.
