Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

Life on Earth depends on the ability of cells to duplicate their genetic material, encoded in DNA molecules, and pass this information on to the next generation. Elucidation of the molecular mechanism ...

CRISPR-Cas systems are adaptive immune systems found in prokaryotes that defend against invading nucleic acids through CRISPR ...

Every living organism has DNA, and every living organism engages in DNA replication, the process by which DNA makes an exact copy of itself during cell division. While it's a tried-and-true process, ...

Previous researches on DNA included topics of bases, base-pairing, hydrogen bonds, structure, base sequence, dynamics, ...

Huilin Li, Ph.D., of Van Andel Institute DNA replication is a tightly controlled process that copies the genetic code, allowing its instructions to be conveyed from one generation of cells to the next ...

DNA replication origins serve as sites of replicative helicase loading. In all eukaryotes, the six-subunit origin recognition complex (Orc1-6; ORC) recognizes the replication origin. During late ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

Scientists at the University of Leicester have captured the first detailed "molecular movie" showing DNA being unzipped at the atomic level – revealing how cells begin the crucial process of copying ...
