• B. The cell ready to update align DNA
• C. A host cell without cell wall
• D. Agrobacterium cell

Answer 1

Answer: (D)

Agrobacterium cell

Option 'D' is correct.

Competent host is recombinant DNA technology is Agrobacterium cell. Competent host cell is required for transformation with recombinant DNA. Different types of available host cells are like E.cola, yeast, animal and plant cells. Eukaryotic cells will be preferred host, yeast-cells are preferred because this are simple eukaryotic organism and like bacteria are single-celles, easy to grow manipulated. Bacteria also acts enabled to pick up the recombinant-DNA.
