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 at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the ...

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 a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

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 ...

James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...

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 ...

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 ...
