Look deep into nature, and then you will understand everything better.. Albert Einstein. . one-gene, one-enzyme hypothesis. Many enzymes are composed of more than one polypeptide chain, or subunit (that is, they have a quaternary structure). In this case, each polypeptide chain is specified by its own separate gene. Thus, it is more correct to speak of a one-gene, one-polypeptide relationship: The function of a gene is to control the production of a single, specific polypeptide.. 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. Replication. Functions (Stores and provides copies of genetic material- genes). Blueprint (genes) for Protein Synthesis (Enzymes and cell building blocks). Francis Crick. RNA (Ribonucleic Acid). Why do we need RNA?.  RNA and Protein Synthesis. Genes. are coded . DNA. instructions that control the production of . proteins. . DNA is like the master plan.. RNA. contains coded information for making proteins.. RNA . Objectives. Explain the purpose and process of transcription and translation. Recognize that gene expression is a regulated process. Describe the roles of DNA and RNA in cell differentiation. Identify and illustrate changes in DNA and evaluate the significance of these changes. 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 . .

What the DNA actually says is what types of proteins to make, when to make them, & how much of them to make.. 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.. codons.  that define specific amino acids. Many questions pertaining to this genetic code were posed in the late 1950's:. • How many RNA nucleotide bases designate a specific amino acid?. If separate groups of nucleotides, called .
