Question: What role does the T-DNA region play in Agrobacterium-mediated gene transfer?

Options:

Correct Answer: It carries the gene of interest

Solution:

The T-DNA region of the Agrobacterium plasmid carries the gene of interest that is transferred into the plant cell.

What role does the T-DNA region play in Agrobacterium-mediated gene transfer?

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.
