Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

So-called junk DNA was given that unfortunate nickname because its function was so mysterious. These vast regions of the genome do not code for protein and are made up of highly repetitive sequences.

Our DNA is compacted and arranged into chromosomes, most of which are shaped like X’s. The ends of the chromosomes arms are ...

Pacific Biosciences raised the curtain on two DNA sequencers: its first short-read device, designed to offer new competition to the industry giant Illumina, as well as a machine poised to be an ...
