Verified step by step guidance

Understand the term 'recombinant DNA' by breaking it down: 'recombinant' means 'recombined' or 'joined together,' and 'DNA' refers to the molecule carrying genetic information.

Recall that recombinant DNA technology involves combining DNA from different sources, often from different organisms, to create new genetic combinations.

Evaluate each option by comparing it to the definition of recombinant DNA: DNA found only in prokaryotes is incorrect because recombinant DNA can be made from any organism's DNA.

Recognize that DNA replicated during cell division is simply normal DNA replication, not recombinant DNA.

Identify that recombinant DNA specifically refers to DNA molecules artificially created by joining DNA from two or more different sources, which matches the correct description.
