Practice question
Question
Agobacterium Ti plasmid vectors are used to generate transgenic plants. The following are examples of vir gene encoded proteins that are important for transfer of T-DNA in to plants. A- vir E, single stranded DNA binding protein B- virD2 that generates T-strands C- vir A that sense plant phenolic compounds D- vir F which directs T complex proteins for destruction in proteasome Which one of the following combination of the proteins functions inside the plant cell?
Explanation
agobacterium ti plasmid vectors are used to operates via A, B and D represents established outcome. functional assays validates option D. Other options propose substrate or regulatory direction, inconsistent with published kinetics and mutant phenotypes.
