Introduction to Biological Sciences 110a In class notes for November 28, 2007 Ribosomes have two subunits o When complexed together they have the following designation Bacteria Eukaryotes Intact it is 70s Intact it is 80s 50s and 30s make up the 70s 60s and 40s make up the 80s o The bigger it is the bigger the s is. o From table, know that each subunit has at least one rRNA in it. 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.
