When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

DNA-copying enzymes caught making errors that could reshape DNA writing
Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...
Scientists used a bacterial system called retron to turn DNA into a programmable tool inside living cells, enabling gene ...
DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
The puzzle seems impossible: take a three-billion-letter code and predict what happens if you swap a single letter. The code we’re talking about—the human genome—stores most of its instructions in ...
R-loops are structures that form when a strand of RNA (red) forms a stable structure with double-stranded DNA, causing one strand of the DNA to form a loop. R-loops are associated with gene ...
