Presentation Transcript

  1. Nukleinsyra DNA Deoxyribonukleinsyra RNA Ribonukleinsyra

  2. DNA -kromosom • http://www.youtube.com/watch?v=DDc7yFCsj0Y

  3. The human genome projectHugo • HUGO Human genome organisation • Baspar i genomet 3 000 000 000 • 20 300 gener • 3% proteinkodande sekvens

  4. Räkneexempel • 3 000 000 000 bp i genomet • = 1 500 000 000 bp enkelsträngat DNA • = 500 000 000 möjliga codon • 3 baser/ sekund skulle ta 47,6 år @8h/d-7d/vecka

  5. ATP adenosine triphosphate • Energi förvaras i fosfatbindningar

  6. Länkning Ryggrad (backbone)

  7. Vätebindningar Komplementära baspar

  8. Länkning av nukleotider till nukleinsyra – DNA

  9. Replikation av DNA

  10. Hur läser man DNA? • Intron – ej kodande sekvens • Exon – kodande sekvens • Kodon – 3 baspar kodar för en aminosyra • Lokus – område på gen • Allel – en specifik variant av en geneller område (alla bär 2 alleler en maternal och en paternal)

  11. RNA ribonukleinsyra • Vad skiljer DNA och RNA?

  12. RNA Transkription • RNA-polymeras

  13. Transkription • http://www.youtube.com/watch?v=41_Ne5mS2ls • film

  14. RNA • hnRNA hetronukleärt • mRNA messenger (budbärar) • t-RNA transport • rRNA ribosomalt • SiRNA • MiRNA

  15. t-RNA

  16. r-RNA

  17. Genetisk kod

  18. Transkription Translation
