Naked Genetics - Taking a look inside your genes
Summary: From plants to pathogens, fruit flies to fungi and hamsters to humans, Naked Genetics takes a look at the science of genes. With in-depth interviews, the latest news from the world of genetics, answers to your questions, and our gene of the month, tune in for a look inside your genes...

When it comes to figuring out which genes and genetic variations are linked to particular traits and diseases, there's only one way to do it, and that's to go large, with cohort studies involving hundreds or even thousands of volunteers. We meet the Born In Bradford bunch, a Canadian cohort, and more than a few pairs of twins. Plus, oh my God, they killed our gene of the month!
There's more to life than the four letters of DNA, and our cells use a chemical tag known as DNA methylation to mark out certain parts of the genome, helping cells to remember what they're doing. And, as you might expect, it's pretty important. Plus, how your GCSE success could be encoded in your genes, an important molecular cause of autism identified, and an illuminating gene of the month.
Genes are the instructions that tell our cells what to do, but how do different types of cells know which genes to switch on or off at the right time? The solution lies in epigenetics - the molecular bells and whistles that act on top of our DNA to control gene activity. Plus, a new gene involved in severe obesity, and a mythical gene of the month.
For centuries, breeders have been selecting plants and animals with desirable genetic traits. So how have some of these changes come about, and where will new genetic technologies take our food in the future?
You may not realise it, but all the food you eat has been genetically altered over time by plant and animal breeders, capturing advantageous traits to grow more nutritious and easy-to-farm foods as efficiently and healthily as possible. Maize, or corn as it's often know, is a prime example of this change. Plus, is attractiveness to mosquitoes in your genes? And our gene of the month is small but significant.
There are few things in life as important as the food we eat, but making sure that we guard the genes in our crops for the future is just as important. Plus, we take a look at some of the intellectual property issues surrounding our food, learn squid's surprising secret, and our gene of the month might be a mayor.
Over the past year the Government has unveiled an audacious programme under the banner of Genomics England, aiming to sequence the genomes of 100,000 people affected by cancer and rare genetic diseases. We take a look at some of the practical and ethical issues around the project. Plus, our gene of the month comes from the land of the forever young.
Genetically modified, or GM, crops are a hot topic. Some people are deeply suspicious of the technology while others see it as an effective and efficient way of generating bountiful, healthier harvests. Plus, purple tomatoes, a giant of a gene involved in heart disease, and what's in a name? We take a look at the naming of genes.
How do we learn complex tasks like playing the piano? Why can we remember things better after a good night's sleep? And why do people - and fruit flies - drink again after the hangover from hell? The answers are all in your genes. Plus, why large-scale searches for so-called "genes for schizophrenia" and other psychiatric diseases are turning out to be trickier than we thought, and a gene of the month with a touch of Scottish - or maybe Hollywood - spirit.
For many years scientists have been searching for the mysterious engram - the place in the brain where memories are kept. And thanks to advances in genetics and neurobiology, it looks like they're now getting close to finding it. Plus, contagious cancers in dogs and devils, and our gene of the month prefers the cold.
Every year in the UK more than 330,000 people are diagnosed with cancer. The good news is that more and more are surviving, and there's hope that the new generation of genetic research and targeted therapies will bring more cures in the future. But is cancer a cleverer enemy than we thought? Plus sealion genital cancers, and an over-excited gene of the month.
Could we one day be popping pills that tweak our metabolism and make us live longer? It's not as far off as you might think. Plus, the cow genome goes large, bat flu flies into focus, and an untidy gene of the month.
Every day we get older, and whether you're desperately resisting the march of time, or embracing the ageing process, most of us would agree we want to live as long, healthy lives as possible. We'll be finding out how genetics research can help. Plus, making fingers with Alan Turing, growing lizard tails, and a long-lived gene of the month.
From the beauty of a sunset or the ugliness of war to the smile on a loved one's face, our eyes bring us all kinds of information about the world around us. now researchers are working to develop new therapies for people who have lost this precious sense. Plus, smelling elephants, marmoset twins, and an all-seeing gene of the month.
Whether we like it or not, we're heading further along the road of genetic testing, not just for single genes but for complex diseases and even ancestry. But can the results of gene tests change our behaviour? Plus colouring crows, electric eels, gluing chromosomes and a sketchy gene of the month.
