This chapter describes the cell cycle, DNA replication, and repair. The cell cycle is the period during which the cell duplicates its entire contents such that on subsequent cell division, each daughter cell contains all the material originally present in the parent cell at the beginning of its...
The replication of the genetic material, DNA, and its subsequent distribution to two daughter cells are perhaps the most fundamental processes carried out by living organisms, ensuring that each cell generation contains the same set of information as the previous cell generation. At the most basic ...
Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells. The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase,...

Replication origins in eukaryotic cells never fire more than once in a given S phase. Here, we summarize the role of cyclin–dependent kinases in limiting DNA replication origin usage to once per cell cycle in the budding yeast Saccharomyces cerevisiae. We have examined the role of different cyc...
During which stage of the cell cycle is the DNA replicated? a. Mitosis. b. S. c. G2. d. Cytokinesis. Cell Cycle: The cell cycle is the steps taken during a cells life cycle. The cell cycle is divided into interphase, mitosis and cytokinesis. The...
Moreover, the SLAP1 splicing factor is required to maintain VEX2 sequestration and the VEX1 and VEX2 association is dynamic during DNA synthesis. The VEX1-2 bridge is self-limiting We next sought further insights into VEX2 protein-protein interactions, using a cell line in which both VEX2-...
The cell cycle is the complex sequence of events by which cells grow and divide. In eukaryotic cells, this process includes a series of four distinct phases.
expression and that the effect of each treatment was markedly different between GECs and podocytes. HG treatment led to upregulation of “immediate early response” genes, particularly those of the EGR family, as well as genes involved in inflammatory responses (in GECs) or DNA replication/cell ...
First, cellular dormancy, means that each cancer cell shows cell cycle arrest. The second is tumor dormancy when in cancer a balance between growth and apoptosis rates appears. The length of dormancy is long in prostate cancer or in hormone dependent breast cancer, whereas in triple negative ...
