When the fork stalls due to an obstacle on the DNA (Figure 1), the cell activates the replication checkpoint to send a signal to arrest the progression of the cell cycle. Another example of ...

Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up ...

TAg expression and viral replication occurred after the first round of host DNA replication, and TAg expression also depended on the cell's going through a first round of replication. If Needham ...

and creates a cellular milieu that promotes the resolution of replication fork blocks before entry into mitosis by inducing cell cycle arrest, dNTP production, and the transcription of DNA repair ...

While the multiciliation cycle followed the transcriptional phases of the traditional cell cycle, DNA replication did not occur and the cells did not end up dividing. Instead, they grew a bunch of ...

This key difference could affect how genes are accessed and used by the cell to regulate important processes like gene expression and DNA replication. "These differences in chromatin behavior are ...
