Abstract:
DNA replication ensures the precise transmission of genetic information from parent to daughter cells. In eukaryotes, this process involves the replication of every base pair within a highly complex chromatin environment, encompassing multiple levels of chromatin structure and various chromatin metabolic processes. Recent evidence has demonstrated that DNA replication is strictly regulated in both temporal and spatial dimensions by factors such as 3D genome structure and transcription, which is crucial for maintaining genomic stability in each cell cycle. In this review, we discuss the diverse mechanisms that govern eukaryotic DNA replication, emphasizing the roles of chromatin architecture and transcriptional activity within the mammalian chromatin landscape. These insights provide a foundation for future investigations in this field.

The basic unit of the chromatin is the nucleosome, consisting of DNA wrapped around octameric histone proteins and short stretches of linker DNA separating individual nucleosomes. The histone proteins within the nucleosome have their...

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.

The Replisome
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...
