PPT-DNA, RNA, and Protein Synthesis

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. genotype to phenotype. 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.. 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. . 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:. . Dr. Shumaila Asim. Lecture # 2. 1. RNA Synthesis . (Transcription). . Introduction. First step in gene expression . RNA is involved in the transfer of genetic information stored in DNA to proteins . CHM . 341. Suroviec. . Fall . 2016. I. . Nucleotides, Nucleic Acids and Bases. Bases. Planar, aromatic, heterocyclic. Purine (2 rings). Pyrimidine (1 ring) . Adenine (A). Guanine (G). Thyamine (T). 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. Chapter . 17.1-17.3. Important Terms to Know…. 25% of students confuse these terms in . FRQs!!. Replication. Copying of DNA . prior to cell division. (DNA .  DNA). Not prior to transcription. !. 69NB. Directions:. Using one half of the a DNA helix, show what the correct pairing would be, skip lines.. ATT CGT TAC CAC CTC. TAT TAG GCA ATA TTC. GTG TGA TTA ATA GCC. CTA AAG GAA TAG GAT. GAT GAA TAC CCA CGA. 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.. .. The length of the transcription bubble is about 12 to 14 . bp. , but the length of the RNA–DNA hybrid within the bubble is only 8 to 9 . bp. . As the enzyme moves along the template, the DNA duplex reforms. 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.. 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.
