It has long been accepted that a gene's protein-coding information is contained in only one of its two DNA strands. But in 22 February Nature, Victor Corces and co-workers at the Department of Biology ...

A graphic of a purple and magenta Cas9 protein, which is a somewhat round, but uneven, ball, bound to a yellow and orange ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

When AlphaFold solved the protein-folding problem in 2020, it showed that artificial intelligence could crack one of biology’s deepest mysteries: how a string of amino acids folds itself into a ...

Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...

Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development ...

Telomeres are repetitive sequences of DNA that can be found at the ends of chromosomes, where they form a kind of protective cap. Telomeres get shorter every time a cell divides, and they are thought ...

Ribbon structure of the BRCA2 protein. Mutations in the BRCA2 gene are linked to increased risk of breast cancer. New work from UC Davis shows how individual BRCA2 proteins work to repair damaged DNA, ...

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 ...

Researchers at Pohang University of Science and Technology (POSTECH) have built a platform that steers cell behavior using ...
