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.

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.

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? This is where nature, the mad scientist, comes in.

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 theory of English physicist, Francis Crick in the 1950s, the early principles he was trying to convey, and then brings us up to speed on what we know about the information flow of DNA, RNA and protein biological processes, today.

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.

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.

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.

Today we understand much more detail about the structure of DNA. It turns out that Watson, Crick, Wilkins, Franklin, and the many others involved gave essentially the correct answer about the DNA molecule and how it is structured.
