It allows the labeling of a high number of cells within one experiment with little effort. The fraction of replication-labeled cells depends on the density of scratches applied and number of cells that are in S phase.Lothar Schermelleh
Labeling DNA Replication Foci to Visualize Chromosome Territories In Vivo.doi:10.1002/cpcb.19While a detailed understanding of chromatin dynamics is needed to explain how higher-order chromatin organization influences nuclear function, the molecular principles that regulate chromatin mobility in mammalian ...

1. Chemical basis of DNA replication To talk about the principle of DNA replication, we need to start with the structure of DNA. DNA is composed of deoxyribonucleotides, and its basic unit deoxyribonucleotides is composed of deoxyribose, base and phosphate groups. The phosphate end is defined...

Nucleosome assembly during DNA replication occurs in a stepwise fashion. Early studies using a chemical cross-linking technique combined with radioisotope labeling methods demonstrated that parental histone H3–H4, which is one of the major carriers of epigenetic information, needs to be recycled during...
