A piece of DNA that contains sequences from two or more different organisms is called
A) species-specific DNA.
B) recombinant DNA.
C) transgenic DNA.
D) semiconservative DNA.
E) inverse DNA.
Recombinant DNA
DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) to bring together genetic material from multiple sources.
Species-Specific DNA
Sequences of DNA that are characteristic of and vary between different species, used for identification and study of genetic diversity.
Transgenic DNA
DNA that has been genetically engineered, incorporating genes from other species, often used to give organisms new traits.
- Understand the instruments and methodologies applied in genetic engineering, such as vectors, restriction enzymes, and protoplasts, for generating recombinant DNA.

Final Answer :
B
Explanation :
Recombinant DNA is formed by combining DNA sequences from different organisms. Transgenic DNA refers specifically to recombinant DNA that has been inserted into an organism's genome. Species-specific DNA refers to DNA that is unique to a particular species and is not necessarily from multiple organisms. Semiconservative DNA is a term used to describe DNA replication, not a type of DNA itself. Inverse DNA is not a scientific term.
