Hoofdstuk 4: eiwitsynthese

Verloop

Gewilde resultaat: eiwit

Wat is een eiwit? Specifieke volgorde van AZ

 Info hiervoor? In de kern  chromosomen  genen  DNA
1. Kopie maken van de info uit de kern
2. Enzym nodig om 2 strengen uit elkaar te halen  1 streng af te lezen
 Enzym= RNA polymerase
 3’  5’ streng af lezen
3. Nieuwe streng maken 5’  3’
4. Strengen aan elkaar hechten  COMPLEMENTARITEITSPRINCIPE
5. Streng verlaat de kern, vertalen naar eiwittaal  translatie
6. streng naar RER brengen, dicht bij de kern
7. adhv ribosen streng vertalen
 kleine subeenheid: vastnemen en aflezen
 grote subeenheid: vertalen en afkoppelen
 adhv startcodons en stopcodons
 resultaat? Afgekoppelde codons
8. tRNA nodig  codons aan elkaar te binden
 = een klaverbladstructuur
 ene kant anticodon andere kant codon binden
9. transcriptie  mRNA brengt tRNA in de grote subeenheid v ribosoom
10. eiwit bind alle codons aaneen
11. gewilde resultaat bereikt : specifieke sequentie aan AZ = EIWIT



De structuur van een gen

- Chromosmen met daarop genen
 Eiwitten + DNA
- DNA
= erfelijkheidscode
 Nucleotiden (desoxyribose) +
fosfaatgroep + N-base
 4 soorten basen
adenine, guanine,
(dubbeleringstructuur)
cytosine, thymine (enkele ringstructuur)
 Duplexstructuur/dubbele helix
=2 lange ketens = desoxyribose + fosfaatgroep
=treden = 2 N-basen verbonden door H-bruggen
 Verdubbelen DNA (info in de volgorde van de basen)
 Verbreken H-bruggen
2 losse strengen
 basen: A complementair met T en G complementair met C
 aan elke streng een nieuwe gevormd worden die complementair is
