In the study of life’s origins, a key challenge is understanding how RNA could have polymerized and subsequently replicated in early Earth. We present a theoretical and computational framework to ...

Mitochondrial deoxyribonucleic acid (mtDNA) is essential for cellular energy production and overall cell function. Abnormalities in mtDNA are linked to various diseases and are also implicated in ...

A team has unlocked a decades old mystery about how a critical cellular process called DNA replication is regulated. A team of Florida State University researchers has unlocked a decades-old mystery ...

The DNA replication process is constantly challenged by exogenous and endogenous sources of genotoxic stress, including DNA lesions, unusual secondary DNA structures, limiting nucleotide levels and ...

Researchers have identified the mechanism used by the helicase ring to thread around and separate entwined DNA strands in the replication process. DNA replication is a complex process in which a ...

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 aging, cancer, ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...

Exactly how does the DNA replication process start? USC scientists provide the first snapshot of how double-helix DNA begins to unwind and replicate after certain proteins put on the “squeeze.” A ring ...

DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell ...
