The correlation between termination of DNA replication and cell division in Escherichia coli was studied under conditions in which DNA replication was slowed down without inducing SOS functions. The experimental system used involved amino acid starvation of synchronized cells in the presence of methionine...
DNA is the genetic material of the cell and holds all the information necessary for life. During DNA replication, DNA is copied to form two identical molecules that can be used during cell division. Answer and Explanation:1 DNA replication is accurate because of the complementary pairing of nucl...
How replication and division processes are coordinated in the cell cycle is a fundamental yet poorly understood question in cell biology. In Escherichia coliTiruvadi-Krishnan, SriramMnnik, JaanaKar, PrathithaLin, JieAmir, ArielMannik, Jaan
DNA replication and the division cycle in Escherichia coli of replication is initiated at about the time when the over-all rate of DNA synthesis doubles; i.e., some 20 to 25 minutes before cell division. We... DJ Clark,O Maal?E - 《Journal of Molecular Biology》 被引量: 1663发表: ...
(Fig.4e). These results reveal a global transcriptional telomere signature negatively correlated with hTL. This signature can be extended with most genes involved in cell division, DNA repair, DNA replication, and cell cycle since they also exhibit a negative correlation with hTL and a positive ...
Cyclin-dependent kinase 1 (Cdk1) is essential for cell division and suppression of DNA re-replication but not for liver regeneration Cyclin-dependent kinase 1 (Cdk1) is an archetypical kinase and a central regulator that drives cells through G2 phase and mitosis. Knockouts of Cdk2, Cdk3,.....
-cell level is often attributed to the stochastic activation and binding of transcription factors,13 the synthesis of mRNAs and proteins in bursts,11 the random partitioning of molecules between sister cells during cell division,14 and changes in gene copy number over the course of DNA replication...
Our prior analyses provided a sense of functions that were gained or lost by different strains of A. pittii; however, they do not necessarily capture difficult-to-annotate sequences (i.e., genetic dark matter) or provide a sense of gene-level (or mutational-level) similarity between isolates...
In all cases, cells in the radicle had divided just prior to completion of germination in ABA-treated seeds (Fig. 2C,E), while embryos completed germination in the absence of the activation of cell divisions in PAC-imbibed seeds (Fig. 2D,F). These observations demonstrate that each ...
The genome divides and segregates in a manner that is dependent on the cell cycle, prior to the division of the apicoplast and the cell (Striepen et al., 2000). However, it has been technically difficult to visualise the genome during this process of partitioning in T. gondii. This ...
