What are Ribosomes?. Found in every cell. Protein Synthesizers of the cell. Located on the Rough ER and in the cytoplasm in eukaryotic cells and move freely in prokaryotic cells. They are a combination of RNA and proteins . Chapter 13 . (Pgs 360-389 Miller and Levine Biology text. ). http://www.youtube.com/watch?v=suN-sV0cT6c. . Where have we seen DNA being replicated?. MITOSIS AND . MEIOSIS. Proteins are molecules that are necessary for virtually every activity in your body. Some of the Biological Functions of Proteins include:. A journey into a cell.. By: Aaron Logan Mancuso. What is a Ribosome?. Ribosomes are cell organelles that consist of . RNA and proteins.. They make . proteins by joining amino acids together. .. Depending on the protein production level of a particular cell, ribosomes may number in the . Transcription Review. Codons. Ribosomes. tRNA. Start and Stop Codons. Protein synthesis. TeachWithFergy . Preview File. Please enjoy this preview of your Power Point. . Some slides appear blank because they have been removed.. Protein Synthesis. Protein Synthesis. DNA contains . genes. sequences . of nucleotide bases. These Genes code for . polypeptides (proteins). Proteins. are. used . to build cells and do much of the work inside cells. Chapter 13: RNA and Protein Synthesis. The Genetic Code. The first step in decoding genetic messages is transcribing DNA into RNA. The RNA contains the code for making a protein. Proteins are made by joining together amino acids into long chains called . .. Ribosomes. Made of ribosomal RNA and protein. Synthesized by nucleolus of cell. Proteins from cytoplasm are brought to nucleus and made with . rRNA. into large and small subunits of ribosomes. Subunits leave the nucleus and assemble into ribosomes. Learning Outcomes. At the end of this . topic . you should be able to . . Outline the steps in protein synthesis. Know that . DNA contains the code for protein. Know . that enzymes unwind the DNA. Know .
