Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...
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 ...
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 ...
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 ...
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 made simple for bio students
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 ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
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 ...

Rethinking how nucleoside supplementation speeds up DNA replication: It's not just about having enough
DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...
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 ...
Drs Ursula A. Matulonis and Joyce F. Liu discuss targeting DNA damage and repair and replication stress in endometrial cancer. Drs Ursula A. Matulonis and Panagiotis A. Konstantinopoulos discuss ...
DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
