A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
They were discovered over 100 years ago – but we still don't know exactly what genes are.
The genes in our cells' mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn't derailed by mutations.
The short answer is no. An individual of one species cannot, during its lifetime, turn into another species. But your question helps us think about life, evolution and what it means to be human.
A new study has assessed the links between cholesterol and cognitive function.
Scientists may have discovered why cancer incidence rises with age, and it's got more to do with the immune system than people thought.
A new paper describes the idea of "genetic nurture", where parents’ genes, even those not passed on to their child, have major effects on kids’ health and educational attainment.
AML can kill with surprising rapidity. Luckily new treatments are on the horizon.
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
Like it or not, evidence now shows that men and women differ genetically far more profoundly that we previously recognised. An analysis from the 2017 winner of the Prime Minister's Prize for Science.
The 2017 Prime Minister's Science Prize winner is genetic researcher Professor Jenny Graves, well known for her 2002 suggestion that the male Y chromosome will self-destruct.
Whether you're a night owl or a morning lark, circadian rhythms control just about every aspect of your health.
Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
Inserting a random DNA mishmash into a plant or bacterium directs it to make a novel protein. Sifting through the resulting molecules, researchers may find ones have medical or agricultural uses.
Parents' DNA try to manipulate one another in a bid to shape junior in their mould.
Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
Most people will be much better off putting the money spent on a genetic test towards a gym membership, or a pair of trainers.
Research finds genes account for 50% of differences in social mobility.
William Isdale talks to Professor Julian Savulescu about the ethical implications of geneticaly modifying humans.
Converting a DNA sequence into an audio could help us learn something useful about it, like where mutations occur.
