Explanation for the incorrect options:

Option A:

Cloning is the process of generating a genetically identical copy of a cell or an entire organism.

Option B:

A vector, as related to molecular biology, is a DNA molecule (often plasmid or virus) that is used as a vehicle to carry a particular DNA segment or strand into a host cell as a part of a cloning or recombinant DNA technique.

Option D:

Retroviruses are viruses with RNA as genetic material.

Final answer: Nucleic acid segment which is used to find the position of a gene and it forms a hybrid with this gene would be Probe.
