Gene probes are crucial tools in genetic research, primarily used to identify specific DNA sequences within a complex mixture of genetic material. They are typically short strands of DNA or RNA that are complementary to the target sequence of interest. When a gene probe binds to its complementary sequence, it can be detected, which allows researchers to determine the presence, absence, or quantity of specific genes or genetic markers.

This capability is particularly valuable in various applications, such as diagnosing genetic disorders, screening for mutations, and conducting research on gene expression. By labeling gene probes with fluorescent tags or radioactive isotopes, scientists can easily visualize the binding events and gain insights into genetic organization and function.

By understanding the specific sequences that gene probes can target, researchers leverage this technology to unravel complex genetic information and contribute to advancements in fields such as molecular biology, genetics, and biotechnology.
