Question

Which molecular diagnostic tool relies on the hybridisation of labelled single-stranded DNA to detect specific complementary sequences or mutant alleles?

Options

• ELISA

• DNA probe

• Melt-in-the-mouth assay

• Subunit precipitation

Answer 1

A DNA probe is a labelled single-stranded DNA or RNA segment used to identify complementary target sequences or mutant alleles in a sample through molecular hybridisation.
