In what part of the cell cycle does DNA replication occur? What is leading strand in DNA replication? What happens if there is a mistake in DNA replication? What are the 3 steps of DNA replication? Why does DNA replication occur prior to mitosis?
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...

1.Understanding the Cell Cycle: The cell cycle is divided into two main phases: the M phase (mitotic phase) and interphase. Interphase is further divided into three phases: G1, S, and G2. 2.G1 Phase: In the G1 phase, the cell is metabolically active and prepares for DNA replication....
All base pairs in the genome are replicated during the DNA synthesis phase of the cell cycle, but only some of the base pairs are transcribed into RNA. How is it determined which base pairs of the genome are transcribed into RNA? 在细胞周期的DNA合成期,基因组中所有的碱基对都被复制,但只有...
This periodicity does not appear to be coupled to a specific age in the cycle, but could be associated with the achievement of a specific cell mass per plasmid. During temperature shifts of a dnaC(Ts) mutant, the miniP1 plasmid and pBR322 replicated with similar patterns that differed from...
cell genome replicated randomly during S-phase we conclude that the integrated plasmid DNA is either replicated from a chromosomal origin in the neighborhood of its integration site or that inserts are replicated from their own origins and the timing of replication is determined by flanking sequences...
Cell division is the basis for the propagation of life and requires accurate duplication of all genetic information. DNA damage created during replication (replication stress) is a major cause of cancer, premature aging and a spectrum of other human diso
We employed an in situ Hi-C approach to follow the 3D organization of the fission yeast genome during the cell cycle. We demonstrate that during mitosis, large domains of 300 kb–1 Mb are formed by condensin. This mitotic domain organization does not suddenly dissolve, but gradually ...
Although cohesin can load onto chromosomes throughout the cell cycle, it only builds cohesion during S phase. A key question is whether cohesion is generated by conversion of cohesin complexes associated with un-replicated DNAs ahead of replication forks into cohesive structures behind them, or ...
