The video introduces genetic screening, explaining how DNA sequencing helps identify mutations that cause diseases. It details the process of genetic screening using DNA probes to locate specific alleles. The video covers hybridization, detection of mutant alleles, and screening for multiple diseases using DNA probes on a glass slide. It concludes with a summary and resources for further learning.
