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 ...

Someone asked “What is a genetics fact that not a lot of people know?” and people detailed their best bits of info.

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During ...

DNA polymerases play a central role in maintenance of genetic information, and the structures of polymerases in complex with DNA and dNTP provide valuable insights into mechanisms utilized by DNA ...

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 cells of palm trees, humans, and some single-celled microorganisms, DNA gets bent the same way. Now, by studying the 3-D structure of proteins bound to DNA in microbes called Archaea, CU ...

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 ...

Researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...
