Which option correct 2/4
Dear Student,
Chimaeric DNA means
DNA molecules in which foreign DNA molecule has been inserted are sometimes referred to as chimeric DNA. In mythology chimera was a creature with the head of a lion, body of a goat and tail of a serpent. Since recombinant DNA contains some DNA from other source it is sometimes called as chimeric DNA.
Now as the cDNA of interest is ligated with the plasmid of the bacterium, therefore, it forms a chimaeric DNA (having DNA from different organisms)
Therefore, the correct option is '2'.
