A molecule of tRNA includes a sequence of three nitrogenous bases called an anticodon. What is the role of
the anticodon in the process of translation?
A The anticodon binds to a specific amino acid.
B The anticodon binds to a codon on mRNA.
The anticodon binds to the promoter, a region of DNA.
D The anticodon binds to a codon on rRNA.

Eutrophication caused by human nutrient pollution.

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.

Idon’t understand this can someone give me the answer? you
