The cellular life cycle, also called the cell cycle, includes many processes necessary for successful self-replication ... of proteins scrutinize the cell's DNA, making sure it is structurally ...
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 ...
Harvest cells, want good single cell suspension Count cells Dispense aliquots of 1 million cells into labeled tubes Add 5 ml PBS and centrifuge for 5 min at 400 x g. Re-suspend cell pellet in 300 ul ...
Replication of DNA DNA replication is the process by which a cell makes an identical copy of its DNA. Gene expression Only a fraction of the genes possessed by any particular cell will be expressed.
We also discovered that this breakage mechanism only occurs at the beginning of the cell cycle phase, when DNA replication ...
The precision of this process depends in large measure upon stringent regulatory mechanisms that couple DNA replication to cell cycle progression. Initiation must be triggered at the appropriate time ...
Exonuclease action of replicative polymerase gamma drives damage-induced mitochondrial DNA clearance
How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...
When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...
“If you impose a structure on it, which is this replication-driven cell cycle structure, then suddenly it goes from ... and some regions of the DNA are more tightly packaged than others, so this form ...
Accurate transmission of the genetic information requires complete duplication of the chromosomal DNA each cell division cycle. However, the idea that replication forks would form at origins of DNA ...

Analysis provides new insights into the replication of BK polyomavirus, a major cause of kidney transplant failureTAg 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 ...
The following is a summary of “Clinical significance and pro-oncogenic function of DBF4 in clear cell renal cell carcinoma,” published in the January 2025 issue of Urology by Chen et al. Clear cell ...
