Hoofdstuk 7: Moleculaire genetica
• Gen = erfelijke info voor synthese van 1 eiwit
• Allel = verschillende vorm van een gen
• Genetica: erfelijkheidsleer
→ genotype, fenotype, informatieoverdracht
• Genoom: geheel van erfelijk materiaal in een organisme
• Klonen: identieke nakomelingen v/e organisme of DNA-moleculen
• Epigenetica: overerfbare variatie die niet te wijten is aan DNA-sequentie maar aan gen
‘imprints’, RNA- of eiwitveranderingen
• Gencentrisme: focus op gen
• Reductionisme: een biologisch wezen is niet meer dan een hoop atomen. Iets complex kan
steeds herleid worden naar iets meer fundamenteels
• Holisme: de eigenschappen v/e systeem kunnen niet volledig verklaard worden door de som
van de samenstellende delen
• Contextualising genomics: genoom wordt in een context geplaatst
• Nature ↔ nurture
⤷ aanleg ⤷ omgeving
• EE = enriched environment = stimulerende omgeving
