PPT-Chapter 10 DNA, RNA, and Protein Synthesis

Section 1 Discovery of DNA All living things have DNA Your DNA holds the instructions for everything about you Fredrick Griffith Discovered transformation the transfer of genetic material from one cell to another cell or from one organism to another organism. 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. . DNA from a few Angles. Cell: . Every cell contains a nucleus which is filled with the directions for cell function, DNA. . Chromosome. : . When DNA is tightly coiled and wound it becomes visible in the form of . 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:.  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 . 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. From DNA to Proteins. 2 Types of nucleic acid. DNA- Life’s Code. DNA. -> . RNA . -> . Protein. Influential Scientists. Frederick. Griffith. – Experimented with two forms of . bacteria. From DNA to Proteins. 2 Types of nucleic acid. DNA- Life’s Code. DNA. -> . RNA . -> . Protein. Influential Scientists. Frederick. Griffith. – Experimented with two forms of . bacteria. Transformation. 1928- . Frederick Griffith . was trying to figure out how bacteria made people sick. Pneumonia. Cause of pneumonia was not a chemical poison released by disease causing bacteria. The heat killed bacteria had passed their disease-causing ability to the harmless strain. Gene Expression. When a cell “reads” the DNA, it doesn’t directly say for example blue eyes.. . What the DNA actually says is what types of proteins to make, when to make them, & how much of them to make.. I. RNA [13.1]. A. Describe RNA – . Ribonucleic Acid. B. Differences between DNA and RNA. DNA. RNA. Deoxyribose. Ribose. Double-stranded. Single-stranded. G, C, A, Thymine. G, C, A, Uracil. . C. Types of RNA. 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.. 69NB. Directions:. Using the DNA strand as a template, transcribe mRNA. Make sure to use the correct Nitrogen bases.. ATA CCT TAA CGC GTC. TAT TAG GCA AAA TTC. GTG TGA TTA ATA GCC. CTA AAG GAA TAG GAT. What organelle makes proteins?. Where are these organelles found?. How does the information from DNA get to those organelles?. Protein Synthesis Overview. The information in . DNA . is used to make .
