Naked Genetics - Taking a look inside your genes

Almost every single cell of your body is packed with more than two metres of DNA, containing your genes. But not only does it have to be packed up to fit in there, it also has to be organised and read. Plus, how genetic variations are linked to cancer risk,analysing dinosaur DNA, and an adventurous gene of the month.

It's thought that around one in a hundred children in the UK is somewhere on the autistic spectrum - a complex range of disorders that can be challenging to understand and live with. But recent advances in genetics are bringing hope for new therapies that might help. Plus, we look at the genes underlying Specific Language Impairment, find out why cancer has the X factor, and meet a hopeless-sounding gene of the month.

You've probably heard of DNA, but what do you know about RNA? As well as being the molecule that shuttles information from our genes into our cells, it also plays a huge number of other roles in all cells, from bacteria and viruses to tiny worms, plants and humans. Plus we delve into quadruplex DNA, wonder about the wolf genome, speculate on skin colour and our gene of the month has a literary twist.

The gym is full, the pubs are empty - it can only be January, as a good proportion of the population resolves to shape up and lose weight. But are your efforts going to help you fit into your jeans (with a J), or are you just fighting against your genes (with a G)? Plus, we discuss how genes might jump between cows and snakes, and we've got gout, goats, giant pandas and a glass bottom boat.This is the Naked Genetics podcast for January 2013 with me, Dr Kat Arney, brought to you in association with The Genetics Society, online at genetics.org.uk.

Cancer is literally the enemy within us -it starts when our own cells get damaged and go rogue, multiplying out of control and spreading around body. But how can we use new genetic knowledge to beat it? Plus, decoding the wheat genome, finding out where birds came from, and our gene of the month is more art than science.

Our world - and our bodies - are teeming with bacteria. And although some of them are friendly, many of them are not. Plus, electrifying news about bacterial nanowires, cuddly koalas, and counting chromosomes, and our gene of the month is the mindblowing Mind Bomb.

They suck your blood, hitch-hike on your luggage, and are a growing threat to the hotel industry. Bedbugs are a growing problem in the modern jet-set world, and scientists are using genetic techniques to try and understand why. Feeling itchy yet? Plus, we look at the genetics of some other annoying insects, get to the bottom of the recent controversy about junk DNA, and our gene of the month is none other than Superman and his weedier alter-ego Clark Kent.

We've all heard of the genetic code - the letters that spell out the instructions in our DNA. But that's not the whole story. Researchers are increasingly digging into the epigenetic code - the marks that tell cells which genes to use and which to ignore. Plus, we take a look behind the headlines about older fathers and autism, find out what chimps can tell us about our cancer risk, and our gene of the month might be mistaken for a heavy metal band.

It's now over a decade since the human genome was first sequenced, costing over a billion pounds and taking 13 years. Today, we're close to the thousand dollar genome. But what's in a genome, and what can it tell us about our risk of disease? Plus we'll be arguing the age of polar bears, and finding out about fish with skin cancer. And our gene of the month is one for the Trekkies out there - it's Tribbles.

Every biology student is familiar with DNA - the ladder-like blueprint of life built on a backbone of the sugar deoxyribose. Scientists are now hacking this structure to make entirely new DNA-like molecules built on different sugar skeletons, opening an exciting new world of synthetic genetics. Plus, we find out what happens when music has sex, discover why the X chromosome is more than just a number, and our gene of the month is the unfortunate Ken and Barbie.
