In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...

Scientists at Johns Hopkins report they have deciphered the structure and unusual shape of a bacterial protein that prepares segments of DNA for the insertion of so-called jumping genes. The clamshell ...

First came AlphaFold. Now comes AlphaGenome for DNA. When scientists first sequenced the human genome in 2003, they revealed the full set of DNA instructions that make a person. But we still didn’t ...

DNA isn’t just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated—able to read not only the ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the ...

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 ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...
