To date, people have encoded information into DNA the same way nature has, by linking the four nucleotide bases comprising DNA—A, T, C, and G—into a particular genetic sequence.

Many regions help control when and where genes are active. A genetic variant is a change in the DNA sequence. When a variant occurs in reproductive cells, it can be passed from parent to child and ...

Mistakes made during DNA replication can lead to mutations—permanent alterations in the DNA sequence that can have varying effects on the organism, ranging from benign to harmful.

Rather than bacteria, the Earth BioGenome Project, or EBP, is aiming to sequence the genomes of individual eukaryotic creatures—basically, those that keep most of their DNA in a nut-like structure, or ...

Scientists Sequence DNA from a 3,000-Year-Old Brick A chunk of a Mesopotamian palace revealed genes from dozens of ancient plants ...
