Webb10. Predict: Translation starts when a ribosome (the purple structure on the SIMULATION pane) binds to a strand of mRNA. Transfer RNA, or tRNA, begins bringing amino acids into the ribosome. Each tRNA molecule carries only one kind of amino acid. This amino acid is determined by the tRNA’s anticodon, a set of three unpaired bases. WebbA nucleotide in an RNA chain will contain ribose (the five-carbon sugar), one of the four nitrogenous bases (A, U, G, or C), and a phosphate group. Here, we'll take a look at four major types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), and regulatory RNAs. Messenger RNA (mRNA)
