Answer:
The correct answer will be options-B and D
Explanation:
The studies on the history of origin and evolution of life on Earth shows that all the organisms have evolved from a common descendant. This indicates that they possessed the same chemical-genetic or heredity molecule called Nucleic acid whether DNA or RNA.
DNA acts as the universal genetic material as it is present in all organisms except few. The process related to the DNA molecule is the same in all the organisms.
Since in the given question, the transfer of genes to plants via <em>Agrobacterium</em> and then the expression of the gene in plants shows that the passing of DNA has no barrier as DNA is the genetic material and the enzyme RNA polymerase recognized the gene which could help produce the mRNA from the gene.
Thus, options-B and D is the correct answer.
