When scientists refer to the dna to rna to protein pathway, the rna part really represent three types of rna different: messenger rna (mrna), transfer rna (trna) and ribosomal rna (rrna). how is each type of rna to protein production important? ?

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
