A great part of living in the 21st century is that if you have a device that connects to the internet, you have access to hundreds, if not thousands of experts who are often eager to share in-depth ...

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 ...

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.

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 ...

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 ...

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 ...

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 ...

Naked mole-rats are one of nature's most extraordinary creatures. These burrowing rodents can live for up to 37 years, around ten times longer than relatives of a similar size. But what is the secret ...
