Gene probe is a term used to describe a molecular biology technique that is used to identify specific DNA sequences. The technique involves using nucleic acid probes, which are short sequences of either RNA or DNA, to search for complementary DNA sequences in a target sample. Some synonyms for gene probe include genetic probe, nucleic acid probe, and molecular probe. These terms are often used interchangeably to refer to the same technique of identifying DNA sequences. Gene probes are commonly employed in a range of fields including medical research, forensic science and agriculture. They have proven to be highly effective in identifying specific gene sequences and have greatly advanced our understanding of genetics and its practical applications.
