9/13/2011 2 Components of translation • Messenger RNA (mRNA) • Transfer RNAs (tRNAs) • Amino acids • Aminoacyl-tRNA Synthetases • Ribosomes Cytoplasm nucleus Proteins (enzymes, ) Nucleus cytoplasm Ribosome subunits (rRNAs + proteins) mRNAs and tRNAs What Molecules Go through Nuclear Pores? Replication and transcription in nucleus Translation (proteins) in cytoplasm TFs and ribosomal proteins Nucleotides Transfer RNA (t-RNA) Structure (typical tRNA) 17.14 Base pairing forms “stems” (leaves “loops)
