Q

shotgun sequentiebepaling / contig assembly

A

contig = gecombineerd, telkens aan elkaar lassen
> tot 10 000 bp
> partieel digest > library > (semi) random kleiner fragmenten (overlappend)
> seq willekeurige kloons
gaps opvullen via walking

Q

next generation sequencing toepassing

A
  • controle klonering seq controle (nauwk. res mapping, PCR)
  • onbekende ID
  • ID coderen gebied reading frame, intronen
  • expressiesignalen onderzoeken consensusgebied: prom,…
  • DNA-sequentie vgl

Q

pyroscquencing

A

> partiele digest/sonificatie
ligatie adapters dsDNA fragmenten
denatureren
5’ beads binden
emulsie PCR op beads
- water-olie emulsie; amp 1 streng op bead in 1 druppel
1 bead / well
seq primers tegen adapters
seq verlengd
- elke dNTP ingebouwd > PPi vrij > enz reactie
(APS + PPi + ATP-sulfurylase -> ATP)
(ATP + luciferine luciferase -> licht)
inactieveren door apyrase

Q

SOLiD sequencing + tekening

A

> emulsie PCR & binding beads
primer aan adapter
probes met =/= signaal
- eerste 2nt probe matchen, andere 3 niet
gaps 3 nt
3x steeds deletie in adapter
na 5 rondes volledige seq
p74-75

Q

toepassing SOLiD

A
  • resequencing: seq genoom om vgl referentie
    > vgl scaffolding (bestaand seq)
    > polymorphisms & mutaties

Q

waarom sequenering

A
  • basis info > verwerken, uploaden databanken
  • annotatie = ID wat gesequeneerd, voorspelling, afwijkend product
  • genetische verwantschappen tss individen/soorten
