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 ...

Researchers have achieved the most detailed view yet of how DNA folds and functions inside living cells, revealing the physical structures that ...

Scientists at Purdue University and the University of Minnesota have solved the three-dimensional structure of the central component of a biological "motor" that powers the DNA packaging system in a ...

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 ...

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 ...

Neurons are the anatomical and functional unit of the nervous system, regulating both vital functions and higher functions. Among the very few cells in the body that do not regenerate, these cells ...

Every face carries a story, shaped long before birth by a quiet choreography of genes switching on and off at just the right moment. A new study suggests that part of that story reaches far back into ...
