Chapters 16 and 17 Before the end of the semester we will be covering Historical DNA experiments Structure of DNARNA DNA Replication Protein Synthesis Transcription and Translation Mutations. GO TO . BIOINTERACTIVE WEBSITE. DNA replication questions. Why is DNA replication so important?. In what part of the cell cycle does DNA replication occur?. What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?. 36. Which . of the following statements best describes the structure of DNA. ?. A. . Two strands of proteins are held together by sugar . molecules. , . nitrogen bases, and . phosphate groups.. B. . Identify and compare DNA and RNA.. Explain the three types of RNA.. Demonstrate understanding using codon and anticodon sequences.. Objectives. Protein Synthesis. Protein Synthesis. DNA contains . genes. 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. 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. Protein synthesis . is simply the "making of proteins." . In order to make even one protein. the body must seek the aid of messenger RNA, transfer RNA, DNA, amino acids, ribosomes, and multiple enzymes. . 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.
