This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

"The importance of deoxyribonucleic acid (DNA) within living cells is undisputed" (Watson & Crick, 1953). This opening sentence of James Watson and Francis Crick's second major paper, published ...

DNA stands for Deoxyribonucleic Acid. It is the fundamental blueprint of life, containing genetic instructions for traits and ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

Scientists have constructed ''DNA droplets'' comprising designed DNA nanostructures. The droplets exhibit dynamic functions such as fusion, fission, Janus-shape formation, and protein capture. Their ...

Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...

An international research team has determined the first high-resolution structures of the herpes simplex virus origin-binding ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

As one of the inventors of next-generation DNA sequencing, Sir Shankar Balasubramanian could claim to be responsible for a revolution in the life sciences. Balasubramanian and chemist David Klenerman, ...

Companies that make DNA for science labs screen out any requests for dangerous bits of genetic material. But a new study ...

New research reveals that child maltreatment leaves measurable biological “scars” on DNA, altering brain structure and function.
