1.	Which organism can transfer ‘T-DNA’ within plants?(a) Agrobacterium tumifaciens(b) E.coli(c) Aspergillus niger(d) S. typhiI had been asked this question in an online interview.The question is from Tools of Recombinant DNA Technology: Cloning Vectors in chapter Biotechnology Principles and Processes of Biology – Class 12
Answer» The correct option is (a) Agrobacterium tumifaciens The EXPLANATION is: Agrobacterium tumifaciens is the bacteria which TRANSFERS ‘T-DNA’ within plants. It mostly infects DICOT plants. This ‘T-DNA’ is RESPONSIBLE for the formation of transformed cells called tumors from normal PLANT cells.
