We explore the weird and wonderful world of extrachromosomal DNA - what it is, what it does, and why it breaks the normal rules of inheritance.

S6.16 Double helix double crossing? What really happened between Rosalind Franklin, James Watson and Francis Crick?
Professor Matthew Cobb explains what really happened between James Watson, Francis Crick and Rosalind Franklin during the discovery of the double helix structure of DNA.
S3.23 Heat, Stick, Duplicate, Repeat: The Story Of The Polymerase Chain Reaction (PCR)
In this episode we’re taking a look at the story and the characters behind one of the most transformative - and ubiquitous - techniques in modern molecular biology: the polymerase chain reaction.
S3.09 Twisted history: the true story of the double helix
There's more to the story of the double helix than Watson and Crick. We unwind history to uncover some of the less well-known figures behind the discovery of the structure and function of DNA.
S3.05 - Poop, pus and the Manhattan Project: How we learned to spell the genetic alphabet
The genetic code of DNA is written in just four ‘letters’ - A (adenine), C (cytosine), T (thymine) and G (guanine). But where did those strange-sounding names come from?
016 Genetics By Numbers
4, 3, 2, 1, go! We’re unravelling the story of the double helix, cracking the triplet code, and sketching out a Punnett square.
005 - Vegetable soup
In this episode from our series exploring 100 ideas in genetics, we’re digging around in the genetic vegetable patch - from flavourful tomatoes and chunky onion genomes to Mendel’s peas.
004 - Witness the fitness
We’re taking a dive into the world of evolutionary genetics to witness the fitness - we ask whether street smart city-dwelling birds are genetically different from their country bumpkin relatives, how butterflies got their brightly patterned wings, and if today’s genetic research would have blown Darwin’s mind.
