Here's why:
* Probes are short, single-stranded pieces of DNA or RNA that are designed to bind to a specific complementary sequence on a target molecule (often DNA or RNA). They are used in various molecular biology techniques, including:
* DNA hybridization (like Southern blotting)
* PCR (Polymerase Chain Reaction)
* Microarrays
* DNA sequencing
The probe's sequence is carefully chosen to target a specific gene, region, or mutation of interest. The binding of the probe to its target sequence can then be detected using various methods, allowing researchers to identify and analyze specific DNA sequences.
