Quiz zum Vortrag

  1. It contains multiple genes under the control of a single promoter.
  2. It is the way eukaryotes organize genes in their genome.
  3. It is not found in prokaryotes.
  4. It is a name for a set of spliced genes.
  5. Genes within an operon are transcribed continuously and cannot be induced.
  1. β-galactosidase
  2. β-galactoside permease
  3. β-galactoside transacetylase
  4. Lactase
  1. cAMP
  2. cGMP
  3. CAP
  4. Repressor protein
  5. ADP
  1. LacZ cleaves lactose into glucose and galactose.
  2. Both cAMP and allolactose prevent the expressions of Lac operon by binding with the CAP protein.
  3. The Lac operon contains four genes for lactose metabolism.
  4. The Lac repressor binds to the P site to prevent transcription.
  5. The CAP site binds to CAP which prevents transcription and blocks RNA polymerase attachment.
