Chromosomes replicate chromatin condenses
WebMar 2, 2024 · Abstract. Chromatids of mitotic chromosomes were suggested to coil into a helix in early cytological studies and this assumption was recently supported by chromosome conformation capture (3C) sequencing. Still, direct differential visualization of a condensed chromatin fibre confirming the helical model was lacking. WebThe regulation of genome replication, particularly in the context of the cell cycle, has become the predominant area of research in recent years.This work has shown that initiation is the key control point in genome …
