If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist ...

DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

The Polymerase Chain Reaction (PCR) is a technique for the amplification of DNA in vitro (this describes experiments with cells outside their normal environment). PCR amplifies DNA using complementary ...
