Journey into DNA
Each rung of the DNA ladder consists of two bases. In the DNA molecule, A always pairs up with T, and C always pairs up with G. The sides of the DNA ladder consist of a long string of sugar and ...

DNA Replication
Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T). How the bases are arranged in the DNA is what determines the genetic code. When the enzyme has passed the end ...

DNA Is a Structure That Encodes Biological Information
This base-to-base bonding is not random; rather, each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this ...
The shape of molecules to come: A Q&A on designing DNA nanostructures for biomedical applications
An important specialty in this field—and a signature area of study at the University at Albany's RNA Institute—is DNA ...

What Does DNA Stand For, and How Does It Work?
And why do they talk about it so much on CSI? DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base ...

This Shark Lives 400 Years. Its DNA May Explain Why.
Scientists have mapped the genome of the Greenland shark, which could offer clues to the animal’s extreme longevity. By Jonathan Moens The Greenland shark is not exactly charismatic. Its hulking ...
