Biochemists have developed a new strategy for controlling the biological functions of DNA (deoxyribonucleic acid) by means of light and therefore provide a tool to investigate processes which take ...

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 research team led by Zhiping Weng, Ph.D., and Jill Moore, Ph.D."18, at UMass Chan Medical School, has nearly tripled the ...

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 ...

Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...

This image compares three DNA sequencing technologies: Sanger sequencing, Massively Parallel DNA sequencing, and Nanopore DNA sequencing. Sanger sequencing (left) sequences 500-700 bases per reaction ...

Methionine is an amino acid that is used to build molecules important for cell and DNA function. Meat, eggs, fish, and other foods containing protein will have some methionine in them. Amino acids ...

Scientists at The Hospital for Sick Children (SickKids) have revealed a previously overlooked layer of genetic variation that could help explain why people experience disease differently, and why some ...

The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...
