"The importance of deoxyribonucleic acid (DNA) within living cells is undisputed" (Watson & Crick, 1953). This opening sentence of James Watson and Francis Crick's second major paper, published ...

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 ...

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 ...

DNA Full Form: The full name of DNA is Deoxyribonucleic Acid. This molecule holds the complete genetic code of living organisms. The name “Deoxyribonucleic Acid” reflects its part: “Deoxy” points to ...

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 ...

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.

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 ...

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 ...

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 ...
