In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

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.

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 ...

Newly developed artificial intelligence (AI) programs accurately predicted the role of DNA's regulatory elements and three-dimensional (3D) structure based solely on its raw sequence, according to ...

Guided by the work of Rosalind Franklin, James Watson and Francis Crick discovered the the twisted-ladder structure of DNA in 1953, a finding that gave rise to the modern field of molecular biology.

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed. The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a ...

Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

Fifty years ago today, Francis Crick told patrons of the Eagle Pub in Cambridge, England, that he and James Watson had "found the secret of life." That secret -- the structure of DNA -- would lead to ...
