Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments. siu healthstreamDNA synthesis must occur rapidly, as the unpaired base pairs of the DNA strand during replication are vulnerable to harmful mutagens, which can lead to genetic abnormalities, cell disease or even cell death.
