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 ...

As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...

St. Joseph High School biology students have recently been studying DNA structure and function. DNA stands for deoxyribonucleic acid, which is the genetic information inside the cells of the body 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 ...

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 ...

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 ...

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 ...

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 ...

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, ...
