We have long struggled to determine how the first living organisms on Earth came together. Now, surprising evidence hints that poorly understood prions may have been the vital missing ingredient ...

The protein, reverse transcriptase, has become an essential tool for making DNA copies of RNA.

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

Hydrogenases catalyze the reversible splitting and production of hydrogen gas (H2), using complex catalytic cofactors ...

All starting from the same DNA, neurons ultimately take on individual characteristics in the brain and body. Differences in ...

The best time to take digestive enzymes is usually within the first few bites of a meal, Dr. Bedford says. “You want the ...

When a bioactive molecule occurs in nature at trace levels, traditional extraction often means sifting through mountains of biomass for a few grams of ...

Cornell researchers have developed a powerful new biosensor that reveals, in unprecedented detail, how and where kinases – enzymes that control nearly all cellular processes – turn on and off inside ...

NUDT5 enzyme acts as a molecular scaffold that maintains metabolic balance. Inside every cell, a finely tuned metabolic network determines when to build, recycle or stop producing essential molecules.
