Q

Gevolgen in euk

A
  • meestal geen
  • in promotor: ≠ activiteit
  • intronen grote kans geen effect (splice junctions waar int-ex gesplitst)
  • UTR effect translatie efficiëntie & mRNA stabiliteit
  • in coderend> frame shift

Q

qPCR met FRET + tekening

A
  • fluorescent resonance energy transfer
  • flankerende primers
