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 ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...

Scientists are exploring how DNA’s physical structure can store vast amounts of data and encode secure information.

DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...

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 ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint ...

Scientists developed a light-responsive artificial nucleic acid that enables reversible, controllable crosslinking within DNA, opening doors for nanomedicine, DNA nanotechnologies and drug delivery.

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 ...

"By cleverly combining new techniques for analyzing DNA at the level of individual molecules, we can achieve real breakthroughs in research into conditions such as dementia," predicts Professor John ...
