DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Check your ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958? Semiconservative ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

DNA replication is essential for living organisms to faithfully deliver genetic information from parental cells to daughter cells. Many proteins are assembled on the parental DNA to work as ...

In mitosis, DNA replication is initiated through the actions of various multiprotein complexes that recognize the start sites within a chromosome and cause the separation of DNA into two ...

Unlike nuclear DNA, mitochondrial DNA (mtDNA) is circular in nature and organized as mitochondrial nucleoids comprised of DNA-protein complexes that are distributed in the matrix. It is also inherited ...

Life depends on double-stranded DNA unwinding and separating into single strands that can be copied for cell division. Scientists have determined at atomic resolution the structure of machinery that ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...
