Solution
Chimeric DNA is the recombinant DNA molecule or hybrid DNA that carries DNA segments from other sources, i.e., it is the mix of DNA from two different organisms. Uracil is a pyrimidine base which is present in RNA, not in DNA.
DNA strands synthesized using RNA as template are called as complementary DNA (cDNA). This process is carried out by reverse transcription enzyme which copies RNA into DNA; it does not insert foreign DNA.
DNA is a double stranded molecule but is also present as single stranded in some organisms; the single stranded DNA is not a hybrid DNA.
Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands. Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.
So, the correct answer is 'Recombinant DNA'
