Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential ...

The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...

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 ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

Scientists show DNA polymerases can build long, patterned DNA without a template, opening new paths for synthetic biology and ...

A team of researchers at VCU Massey Comprehensive Cancer Center has identified a new pathway through which mutations in the tumor suppressor p53 gene—found very frequently in human tumors—hijack DNA ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

New research has discovered that the molecular machines responsible for copying our DNA have a surprising hidden talent—an ...

Franklin W. Stahl, an American molecular biologist whose landmark 1957-1958 experiment with colleague Matthew Meselson revealed how DNA replicates, helping pave the way for a revolution in genetics ...
