DNA probes

DNA probes are short, specially designed strands of DNA that can specifically attach to a complementary DNA sequence in a sample. They are labeled with a detectable marker, such as a radioactive or fluorescent tag. When the probe binds to its matching sequence, scientists can identify or locate specific genes or genetic material within complex samples. This technique is commonly used in medical diagnostics, genetic research, and forensic science to detect or analyze particular DNA sequences with high precision.
