Protective DNA-protein structure at the ends of linear chromosomes. In most tissues, telomeres shorten every time a cell divides and copies its genetic information.
A new method of determining a person's 'biological age' by examining modifications to their DNA has been unveiled...
Mechanisms directly linking mitochondrial dysfunction to the shortening of telomeres have been discovered, alongside a novel optogenetic technique, which uses light to restore normal function to the mitochondria...
Nearly two decades after the initial release of the human genome sequence, scientists have published the first gap-less, complete sequence...
A sequence of repetitive noncoding DNA that varies considerably in length between humans, has been shown to play a role in ageing and cancer...
Quadruple-stranded DNA structures appear to be evolutionarily conserved in some regions of the genome, indicating they serve an important purpose...
Cancer has plagued humans throughout history. Although it's not a uniquely human affliction, it can be found lurking in virtually every living creature going as far back as the dinosaurs...
Chromosome ends are protected differently in stem cells compared to adult cells...
Exposure to low levels of oxygen in the womb may cause fertility problems for female offspring later in life...
A 'twisted knot' of DNA, known as an i-motif, has been found in living cells for the first time, raising questions about its function...
