RNA synthesis was studied at different phases of the cell cycle of chick embryo fibroblasts, which were synchronized by medium replacement in the confluent phase. The synthesis of DNA started at 4 hr and continued for 8 hr. RNA synthesis increased with time after medium change. The ratio of ...
G1 phase a part of the cell cycle during interphase, lasting from the end of cell division (the M phase) until the start of DNA synthesis (the S phase). G2 phase a relatively quiescent part of the cell cycle during interphase, lasting from the end of DNA synthesis (the S phase) unt...
The Cell Cycle:The cell cycle is the series of phases in the life of a cell. It includes four main phases, G1, S, G2 and M. There is also an optional fifth phase that some cells enter called G0.Answer and Explanation: Become a Study.com member to unlock this answer! Create your...
Besides, G 0 / G 1 phase cells increased with the time, whereas S phase cells decreased during differentiation. CONCLUSION These data demonstrate that during the differentiation process, myoblasts fuse to form myotubes; the cells decrease at the phase of DNA duplication, and a greater number of...
of HeLa cells treated prior to DNA synthesis in the G 1 phase of the cell cycle were not delayed in their progression into the S phase, but showed a dose-dependent inhibition of DNA synthesis when the cells entered the S phase... JJ Roberts,TP Brent,AR Crathorn - 《European Journal of...
Flow cytometry showed that knockdown of Herp arrested granulosa cells at the S phase of the cell cycle. More importantly, ELISA analysis revealed that Herp knockdown significantly upregulated the concentration of estradiol (E2) in the culture supernatants. RT-qPCR was performed to determine the ...
The role of prostaglandin 12 (PGI 2) in the control of DNA synthesis during the cell cycle was investigated in cultured rabbit aortic smooth muscle cells (SMC). SMC at confluency in the G 0 state reached the S phase about 16 h after stimulation with serum, as judged by measurement of [...
transcriptional factor E2F from its complex with Rb(Figs. 1, 2). The released E2F promotes the transcription of several genes necessary for the progression through S phase[2,19,20]. Reviews of cell cycle control have recently been published and provide further insight into cell cycle regulation...
Green synthesis of platinum nanoparticles that induce cell death and G2/M-phase cell cycle arrest in human cervical cancer cells Green synthesis of platinum nanoparticles that induce cell death and G2/M-phase cell cycle arrest in human cervical cancer cells. J Mater Sci Mater Med... AA Alsha...
Due to the disruption of the elongation phase, protein synthesis is suppressed.63 Blocking the 30S subunit: The macrolides and aminoglycosides bound to the 30S subunit prevent the protein synthesis enzyme from working properly. These groups have positive carbohydrate molecules that can enter a ...
