Answer:
<em>Agrobacterium</em> <em>tumefaciens</em> is a gram negative bacteria that is responsible for tumor formation in the different parts of plant body.
Explanation:
It causes crown-gall disease in plant body by transferring it's DNA into the plant body which include Ti plasmid.
There are 3 types of bacteria that form tumor in different plant ares.
<em>Agrobacterium rhizogenes</em>,<em> Agrobacterium tumefaciens</em> strains contain either Ti or Ri plasmid but <em>Agrobacterium vitis</em> contain only Ti plasmid which are virulent.
The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.
TRUE!!!! Idk if this answer is actually for a quiz, but for my opinion and belief, it would be impossible to classify animals and organisms if all of this came from an accident. If this question is for a quiz though, I assume that they will expect you to say False. Mostly to defend their belief. So it's really up to you on what you're gonna go with.
B. The recombinant DNA produced by the combination a vector and the gene of interest are inserted in the E. Coli, which produce multiple copies of this recombinant DNA alone with the chromosomal DNA expresses the gene.
The answer is C
