DNA is the molecular basis of heredity ... Adenine and guanine are double-ring molecules called purines, but cytosine, thymine and uracil are all pyrimidines: single rings. To maintain its ...

The “warm” data in the middle, such as your old photos, can take a few seconds to retrieve. Most data is cold, and a lot of ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

An international team led by UPV/EHU and Biobizkaia reveals the relationship between placental DNA methylation and certain ...

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

Sturgeons are one of the oldest groups of fishes. Sporting an armor of five rows of bony, modified scales called dermal ...

Cambridge University researchers have uncovered evidence that two distinct populations of ancient hominins, separated for ...

New findings show that the mitochondria powering our cells also control the ability of a DNA repair protein to suppress the senescence-associated secretory phenotype (SASP), which causes zombie-like ...

The most famous example of that is in DNA, where they form the double helix we know so well. Making chiral semiconductors has proven to be very difficult, but the researchers have found a way.

"Our immune system function, our gut microbiome, even our very DNA changes," she explained. Allen said without the constant tug of gravity, muscle mass and bone density start to deplete.
