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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
