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 ...

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 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 ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines. DNA ...

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 ...

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 ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the intricate processes ...

A team of researchers at VCU Massey Comprehensive Cancer Center has identified a new pathway through which mutations in the tumor suppressor p53 gene—found very frequently in human tumors—hijack DNA ...
