S Phase
S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Precise and accurate DNA replication is necessary to prevent genetic abnormalities which often lead to cell death or disease. Due to the importance, the regulatory pathways that govern this event in eukaryotes are highly conserved. This conservation makes the study of S-phase in model organisms such as Xenopus laevis embryos and budding yeast relevant to higher organisms.

Famous quotes containing the word phase:
“The Indians feel that each stage is crucial and that the child should be allowed to dwell in each for the appropriate period of time so that every aspect of his being can evolve, just as a plant evolves in the proper time and sequence of the seasons. Otherwise, the child never has a chance to master himself in any one phase of his life.”
—Alan Quetone (20th century)
