    Repeat DNA and Forensic DNA Analysis

    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.

    Ancient Artifacts Inside Your DNA

    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. 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.

    Alternative Splicing - Nature's Mad Scientist

    In the last episode on the central dogma of molecular biology, DNA Dan discussed the information flow of DNA, to RNA, to amino acid sequences that make up proteins. In this episode, Dr. Handley discusses proteins - the work horses of the body, and the extensive roles they play in our bodies. By last known count, there are around 20,000 protein coding genes in the human coding genome that make up and operate the human body. How can these 20,000 genes produce over 100,000 proteins?...

    The Central Dogma of Molecular Biology

    In episodes 2, 3 and 4 of this podcast, we've learned that DNA is determined to be the molecule of inheritance, as well as how its structure is determined. What DNA Dan hasn't yet discussed is what DNA actually does. Or, if DNA is the so called "code of life," how is its code being read? And how is that information put into action? That brings us to the central dogma of molecular biology. In this episode, DNA Dan discusses the "central dogma of molecular biology," information the...

    The Other Human Genome

    If you think back to your early years of biology class, you may remember learning about tiny cellular energy factories, called mitochondira. Mitochondria are microscopic powerhouses hiding within most cells and they play a huge role in our health. Damaged mitochondria can lead to a host of health issues. But healthy mitochondria can result in optimal aging. DNA Dan explains more on mitochondria, and how better understandings may help advance new approaches in the study of some diseases. ------------------------------------------ Join DNA Dan each month as he dives deep into the world of genetics, genomics, DNA, and the future of precision genomic medicine.

    Shotgun Sequencing and the Human Genome Project

    Over the 1960s through 1980s, more was learned about the structure of chromosomes and the functions of some genes. However, we did not have a comprehensive map of the entire human genome. Learn how molecular biology techniques become more sophisticated, and scientists could start determining the nucleotide sequence of small portions of chromosomes. ------------------------------------------ Join DNA Dan each month as he dives deep into the world of genetics, genomics, DNA, and the future of precision genomic medicine.

    How to Get Six Feet of DNA into a Six Micron Suitcase

    In each nucleus of a human cell, the total length of DNA contained in it is about 6 feet long. Now, the size of a nucleus in a human cell is only 6 microns in width. A micron, otherwise called a micrometer, is 1 one-millionth of a meter. To put this in perspective, the average human hair is about 100 micrometers in diameter, and a grain of salt is 500 micrometers in width, give or take.   So how are 6 feet of DNA packed inside such a tiny space? Find out with DNA Dan. ------------------------------------------ Join DNA Dan each month as he dives deep into the world of genetics, genomics, DNA, and the future of precision genomic medicine.
