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....
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...
This mutant is unable to resume cell cycle progression after α–factor arrest. This can be overcome by overexpression of the G1 cyclin, Cln2, revealing a novel role for Esa1 in regulating Start. 展开 关键词: DNA replication origins Cdc6 cyclin–dependent kinase histone acetylation Esa1 ...

AIM To investigate cell cycle and DNA synthesisduring myocytic differentiation. METHODS Murine C2C12 myoblasts were used in this experiment. The control group was cultured in Dulbeccco's modified eagle's medium (DMEM) supplemented with 100 mL·L -1 fetal bovine serum (FBS). Proliferating myoblas...
We transformed synchronized mouse L-thymidine kinase deficient cells with a cloned thymidine kinase gene and carrier DNA at different times in the cell cycle. The frequency of resistant colonies was determined after growth in hypoxanthine-aminopterin-thymidine medium for two weeks (late expression) and...

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...
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 ...
