DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...

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 ...

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 ...

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 ...

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 ...

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.

Neurons are the anatomical and functional unit of the nervous system, regulating both vital functions and higher functions. Among the very few cells in the body that do not regenerate, these cells ...

Researchers from the University of Birmingham have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. The publication of two papers ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
