To prepare a sample, DNA is fragmented into 100–200-base-pair pieces, and then adaptors of known sequence, often poly(A) tails, are attached to the ends of DNA fragments. “We can capture that ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

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 ...

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 analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

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 ...

A new study suggests a far more intricate genetic tapestry is involved in the ultimate ancestry of people in Japan.

based on the idea that DNA can be used as a programmable structural material for the creation of artificial, rationally designed nanostructures. The highly specific nucleotide interaction following ...

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 pairs, DNA carries information between ...

And each time this happens, your entire genetic library—your genome, which totals more than 3 billion base pairs of DNA—has ...
