Section 13-2: Ribosomes and Protein Synthesis: Transcript

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 . Plasma membrane, nucleus and ribosomes. Figure 4.7a. CYTOSKELETON:. NUCLEUS. ENDOPLASMIC RETICULUM (ER). Smooth ER. Rough ER. Flagellum. Centrosome. Microfilaments. Intermediate. filaments. Microvilli. Chapters 16 and 17. Before the end of the semester we will be covering…. Historical DNA experiments. Structure of DNA/RNA. DNA Replication. Protein Synthesis (Transcription and Translation). Mutations. By . Anil Chakka. Reece . Umbarger. Jake . Zevitz. What are ribosomes?. -. Ribosomes are the site of protein synthesis. -Rough ER. -Nucleus (nucleolus) . -Golgi apparatus. -Floating in cytoplasm. Functions of Ribosomes. (endoplasmic reticulum). Dr. Mamoun Ahram. Faculty of Medicine. Second year, Second semester, 2014-2014. Principles of Genetics and Molecular Biology. An overview. Endoplasmic reticulum (ER). It is a network of membrane-enclosed tubules and sacs (. Pete McGee. 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 . Presented by:. TaylorSkye. Goff-Gramando. What is a . Ribosome?. Ribosomes . are the protein . builders . of the cell. .. Tiny organelles that are either freely moving or in small clusters. They are found in all living cells. 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 . .. 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 . Protein Synthesis (Gene Expression) Notes. Proteins . (Review). Proteins make up all . living. materials. Proteins are composed of . amino acids. – there are . 20. . different amino acids. Different . Strategies for organizationClimactic orderarranges the most important/persuasive evidence last since this is what is remembered Problem/solutionestablishes the problem in the introduction then offers Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA. ).. DNA unzips to open the codes that need to be make certain proteins.. The function of the different types of RNA in the cell is to facilitate the task of synthesizing proteins.. An activated . tRNA. with anticodon AGU bonds to serine at the acceptor stem.. Learning Goal .
