Presentation Transcript

  1. DNA Sequencing and Identification of Encoded Genes Kimberley Chinen June 30, 2006 ABE Workshop

  2. Purpose • To determine the order of nucleotides in a segment of DNA • To verify the identity of the encoded gene • PDI2 • GFP

  3. Template Preparation Isolation of Total RNA from Arabidopsis thaliana • Grind and lyse Arabidopsis leaves • Adsorption of total RNA to silica membrane • Removal of contaminants • Quantify RNA

  4. RT-PCR • Reverse Transcription mRNA DNA-RNA hybrid DNA transcript of RNA dsDNA

  5. RT-PCR

  9. Molecular Cloning

  10. Molecular Cloning • Ligate RT-PCR product into pCR4-TOPO cloning vector • Transform E. coli bacteria by heat shock • Amplify and select transformed bacteria using ampicillin treated plates • Isolate plasmid DNA • Run agarose gel electrophoresis • Extract and purify DNA

  11. DNA SEQUENCING • PCR • DNA Sequencing in polyacrylamide gel

  12. DNA Samples Sent in for Sequencing

  13. PCR – 4.5 hours • We Provided • DNA Template • T3 or T7 Primer • They added • dideoxynucleotides – fluorescently labeled • DNA polymerase

  14. T3 and T7 Priming Sites

  15. Deoxynucleotides vs. Dideoxynucleotides

  16. 2. DNA Sequencing of PCR Products in Polyacrylamide Gel PCR products are loaded and run in a polyacrylamide gel to separate the fragments by length in an automated DNA sequencer. A scanner in the sequencer detects the fluorescence and order of the separate bands.
