  1. Ribosomes By: Nick McDonald and Katelin Wilson

  2. Ribosomes, what’s the deal with them? • Cytoplasmic granules composed of RNA and protein • Synthesize Proteins • Protein synthesis takes place in cytoplasm and in the ER • Found in all three Domains of life

  3. The Structure of Ribosomes • Tiny Particles, about 200 Angstrom, one ten billionth of a meter • 37-62% RNA, the rest is made of protein • RNA in Ribosomesiscalled ribosomal RNA

  4. Ribosomal Diseases • Diamond-BlackfanAnemia • Cartilage Hair Hypoplasia • Shwachman-Diamond Syndrome • DyskeratosisCongenita

  5. Questions • What is the purpose of Ribosomes? A. To repair the ER B. To synthesize proteins C. To produce energy for the cell D. All of the above • What does the tRNA do during protein synthesis? A. Provides amino acids B. Dictates the sequence of amino acids C. Binds to the protein D. Releases enzymes to make amino acids
