Fig. 4: The process of establishment of pre-RCs at an S. cerevisiae origin in which the B2 domain is separated from the A and B1 origin elements. This Review focuses on the first step in eukaryotic ...
Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...
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 ...
If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and ...
Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...
For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...
A representative figure showing that HELQ-deficient cells fail to undergo normal fork slowing after MMC (a crosslinking agent) treatment, consistent with defective fork reversal. Every time a cell ...
The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...
DNA is often called the blueprint of life, but what does that really mean? Elizabeth Worthey, Ph.D., associate professor, Department of Genetics in the Heersink School of Medicine, explains everything ...
Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division—a discovery that could lead to new cancer therapies, according to ...
DNA replication in eukaryotic cells is a highly coordinated, multi-step process that ensures precise duplication of the genome prior to cell division. In late mitosis and early G1 phase, the Origin ...
