Question

Chimeric DNA is
A) Gene clone
B) Recombinant DNA
C) Transposon
D)Vector shuttle

Answer 1

Hint:Chimeric DNA is known for their palindromic sequences which results in the production of both the sticky and blunt ends.

Complete answer:
Chimeric DNA is formed by the method of genetic recombination that aids in bringing together genetic material from different sources which otherwise would never be found in that particular genome.
Option A: Gene Clone or a molecular clone is the copy of the isolated piece of the desired DNA gene. Therefore, this is the incorrect option as there are no sticky ends present.
Option B: Recombinant DNA is produced using genetic recombination or molecular cloning technique. They are known to contain genetic materials derived from multiple sources thereby giving rise to a common genome within the newly developed organism. Therefore, this is the correct option.
Option C:Transposons are the mediators that find its applicability for introduction of a foreign DNA within the desired genome. As there are no blunt or sticky ends here, therefore, this is the incorrect option.
Option D: The biotic element that possesses the ability of propagating between two entirely different species is referred to as the vector shuttle. Therefore, this is the incorrect option.

Thus, the correct option is (B) Recombinant DNA.
