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 ...

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 ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA’s shape have an important influence on gene activity and energy production.

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 ...

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

Scientists have discovered how LINE-1, a “jumping gene” that makes up 17% of the human genome, inserts itself into DNA. Using ...

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.
