A single strand of nucleic acid tagged with a radioactive molecule is called

vector

selectable marker

plasmid

probe

Solution

probe

Probes are 15-30 bases long radioactive labelled oligonucleotides (RNA or DNA) used to detect complementary nucleotide sequences, used for diseases diagnosis etc.
