Questions & Step-by-Step Solutions

What role does the T-DNA region play in Agrobacterium-mediated gene transfer?
  • Step 1: Agrobacterium is a type of bacteria that can transfer genes to plants.
  • Step 2: The T-DNA region is a specific part of the Agrobacterium's plasmid (a small DNA molecule).
  • Step 3: The T-DNA region contains the gene that scientists want to introduce into the plant.
  • Step 4: When Agrobacterium infects a plant, it transfers the T-DNA into the plant cell.
  • Step 5: Once inside the plant cell, the T-DNA integrates into the plant's own DNA.
  • Step 6: This allows the plant to express the new gene, which can lead to new traits or characteristics.
