Undervisning er p dansk, men undervisningsmateriale er fortrinsvis p engelsk. Slide 3 Teachers Thomas Nordahl Petersen Rasmus Wernersson Anders Gorm Pedersen Bent Petersen Kasper Nielsen Thomas Blicher Slide 4 This is a hands-on course The major part of the course is computer exercises We get to use the actual methods We get to use live online database Slide 5 Everything is linked from the course programme Slide 6 Readings, slides and hand-outs Power point presentations are uploaded when ready. Updated versions are available the day after. Slide 7 Outline of the course Topics will cover a general introduction to bioinformatics Evolution DNA / Protein and amino acids Alignment and scoring matrices How does it work & what are the numbers Visualization of multiple alignments Phylogenetic trees and logo plots Commonly used databases Uniprot/Genbank & Genome browsers Protein 3D-structure & homology modeling Artificial neural networks & case stories Practical use of bioinformatics tools Sequence information and Logo plots Slide 8 Outline of the course Slide 9 The Amino Acids Asn (N) Asp (D) Gln (Q) Glu (E) His (H) Lys (K) Arg (R) Tyr (Y) Trp (W) Phe (F) Gly (G) Pro (P) Ile (I) Met (M) Leu (L) Ala (A) Val (V) Ser (S) Cys (C) Thr (T) Slide 10 Automated sequencing The major break-through of sequencing has happended through automation. Fluorescent dyes. Laser based scanning. Capillary electrophoresis Computer based base- calling and assembly.
