2. gel electrophoresis: A laboratory technique used to separate DNA, RNA, or proteins based on their size and charge by applying an electric current through a gel matrix.
3. probe: A single-stranded DNA or RNA sequence that is complementary to a specific target sequence and is used to detect the presence of that sequence.
4. primer: A short strand of nucleic acid that provides a starting point for DNA synthesis during PCR or DNA replication.
