Your DNA is constantly changing. And if it weren’t for genetic mutations, evolution wouldn’t exist. So, what would life be ...

Faithful replication of the genome is essential for development, tissue homeostasis and prevention of malignancy. Key steps in eukaryotic DNA replication include the licensing of replication origins, ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...

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 ...

Researchers at the University of Minnesota Medical School have developed a new method called PARTAGE that provides a clearer picture of how the genome is regulated and disrupted in diseases like ...

As recently as the mid-20th century, aging was described by Nobel Prize laureate Peter Medawar as "an unsolved problem in biology." Today, scientists can analyze the activity of thousands of genes in ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

An international research team has recovered ancient human mitochondrial and nuclear DNA directly from cave wall materials in ...

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, ...
