In an experiment, a scientist makes a radioactively labeled probe using human DNA. She then discovers that the probe hybridizes to a small segment of DNA isolated from a plant. What can she conclude from her results?

A. The plant might have a gene that is similar to a human gene.
B. The wrong method was used to detect radioactively labeled DNA.
C. A plant cell has a cell wall, whereas a human cell does not.
D. Plant DNA was accidentally used as a template to make the probe.
