DNA replication is a fundamental process for a cell to ensure that an accurate copy of its genetic material is transmitted to daughter cells at each cell division. Challenges to DNA replication ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

For years, scientists have puzzled over what prompts the intertwined double-helix DNA to open its two strands and then start replication. Knowing this could be the key to understanding how organisms - ...

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 ...

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 ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
