Some can actually have more. They also have ribosomal proteins. You need to know that the 16s rRNA is in the 30s. o The RNA forms a 3-D core. o The yellow region on the 16s on the slide is the 3’ terminal. This is important in how the AUG is recognized. o The three sites for binding are the A site, the P site, and the E site. Ribosomes carry out translation in three steps o Initiation o Elongation o Termination We will start with initiaion in bacteria o We need to distinguish between bacteria and eukaryotes because they have different mechanisms for recognizing the start codon. o
