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 ...

Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

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 ...

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 ...

King Abdullah University of Science & Technology (KAUST)Mar 19 2025 For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for 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 ...

Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

A study conducted in fruit flies by investigators at the University of Alabama at Birmingham has linked a patient variant of ...

Researchers discovered a kinase-driven phosphorylation switch that activates DNA packaging machinery, aligning nucleosomes at ...
