A student wants to construct a plasmid 'BacLight', that when transformed into a bacterium will produce light IF AND ONLY IF the sugar lactose is present in the medium. For this, she uses the following DNA sequences: promoter of repressor ( P _ i ), promoter of lac Z ( P _ z ) , operator ( O ) and repressor gene lacI from the lactose operon; and a structural gene X , which encodes a protein that produces light. The di
Options
- AVector - P _ i - lac I- P ₂- O - Gene X - Vector
- BVector - P _ z - O - Gene X - P _ i - lacI-Vector
- CVector - P _ z - Gene X - O - P _ i - lac I -Vector
- DVector - P _ z - O - P _ i - lacI -Gene X - Vector
