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.

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 ...

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 ...

Describe the basic principle of mitosis (why do cells undergo mitosis?). Diagram how an exact replica of the genetic material is made, including the numbers of chromosomes present at each phase of ...
