From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

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 ...

DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...

It has long been accepted that a gene's protein-coding information is contained in only one of its two DNA strands. But in 22 February Nature, Victor Corces and co-workers at the Department of Biology ...

New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...

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 ...

When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...

If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their daughter ...

PHILADELPHIA – When cells in the human body divide, they must first make accurate copies of their DNA. The DNA replication exercise is one of the most important processes in all living organisms and ...
