Document Summary

Reading the three letter code from the rna and translating it into proteins amino acids. This last step is occurring in eukaryotes in the cytoplasm on factories called ribosomes which go through mrna directed, so it"s based on the message sequence rna, on synthesizing the polypeptide. Translation is the reading of an mrna by a ribosome to assemble amino acids into a polypeptide. This rna does not get translated into a protein it works as an rna. Rna can actually form regions of double strand, these regions are complementary to eachother. Bottom end of trna contains anticodon sequence that pairs with codon in mrnas. Inosine allows any of the other nucleotide to bind to it. It allows this idea of the wobble theory that allows that third nucleotide to be more than one thing. 61 different sense codons do not require 61 different trnas. First two nucleotides of anticodon and codon must match exactly.
