Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that ...

Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab. The genetic alphabet contains just four ...

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a pathogen and then ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

For the first time, the structure of a DNA enzyme complex implicated in infertility and cancer has been obtained using cryo-electron microscopy (cryo-EM). A collaboration of researchers, led by ...

It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own version. Cornell researchers have discovered that DNA packaging structures ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...
