Repeat DNA and Forensic DNA Analysis
12/11/24 • 9 min
This episode of 'Dr. DNA Dan' hosted by Professor Dan Handley from Southern California University of Health Sciences delves into genetics, specifically focusing on short tandem repeats (STRs).
The podcast explains the significance of STRs in forensic DNA testing and paternity tests by measuring the number of repeated sequences in different individuals' genomes. STRs, found across all human chromosomes, are used to match DNA samples in criminal investigations through the CODIS database maintained by the FBI.
The accuracy and real-world challenges of STR analysis, including potential sample contamination and degradation, are discussed to provide a comprehensive understanding of forensic DNA testing.
Tune in each month as DNA Dan dives into the evolving world of genetics, from ancestry and health testing to genetics in mental health and forensics. With over 30 years of experience in genomics, SCU Professor Dan Handley, M.S., Ph.D., brings unique insights into how genetics shapes our lives and the future of precision medicine.

In this episode, Dr. Dan Handley takes us into the fascinating world of proteins—those powerhouse molecules that do the heavy lifting in our bodies. While the human genome contains about 20,000 protein-coding genes, these genes produce over 100,000 different proteins, thanks to nature's incredible complexities. Dr. Handley breaks down the science behind how our genetic code expands to create such diversity in proteins, revealing the intricate processes that keep our bodies running smoothly.
