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 ...

Thanks to increasingly efficient and affordable gene sequencing technologies, we can now chart our genetic blueprint in unprecedented detail. But what does each gene do? Of the roughly 20,000 genes ...

One in every 10 people worldwide is impacted by a rare genetic disease but about 50% of them remain undiagnosed despite rapid increases in genetic technology and testing. Even when a person does have ...

There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

DNA analysis is a crucial tool for identifying harmful pathogens, such as bacteria, viruses, or fungi, that cause infections.

BURBANK, Calif. (KABC) -- Cancer is not a welcome diagnosis, but breakthroughs in genetic sequencing and immunotherapy are making some cancers easier to treat than others. A local father and ...
