DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

It is possible that mistakes were made along the way -- in other words, that a base pair in one DNA molecule doesn't match the corresponding pair in the other molecule. On average, one mistake may ...

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

New crystallography images show that artificial DNA bases take on a surprisingly normal geometry when bound by polymerase. A series of rodent experiments showed that even with abundant food and water, ...

Genome size is the total number of base pairs in an organism. While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always ...

The entire human genome requires three gigabytes of computer data storage space. (One million base pairs of sequence data equals one megabyte of storage space; the human genome has three billion ...

Deletions and duplications of single-base pairs typically arise during homologous recombination and cause diseases. But what happens when a mutation occurs over multiple genes? Deletions involve ...

This can easily be achieved with a copy number calculator, all you need to know is the concentration of DNA in your sample in ng/µl and the length of your template in base pairs. The concentration of ...
