I don't think the quota is the right solution to handle the refugee crisis because I think a strong checkpoint is needed at the borders.
Both dosages induced a strong checkpoint signaling response as evidenced by phosphorylation of ATM and its target proteins.
Many kinetochore mutants provoke a strong checkpoint arrest (e.g., cse4-1, scmif2-3mif2-3, ame1-4, okp1-5, nnf1-17, mtw1-1, stu2-277, dam1-1) but a subset does not (e.g., ndc10-1, cep3-1, spc25-7, ndespite deseveresevere defects in chromosome-MT binding.
Cell cycle progression is strictly controlled by a strong checkpoint system that arrests progression of the cell cycle until either DNA replication is completed or DNA damage is repaired [51].
We thus conclude that replication in the presence of a DSB induces a substantially stronger checkpoint response than that observed in either G1 or G2/M phase.
We propose that Exo1 subsequently generates ssDNA >5 kb from the chromosome end, leading to stronger checkpoint activation that is sufficient to arrest all cells with uncapped telomeres.
How do you reach a hard checkpoint?
Nevertheless, the golden era of film noir the late 1940s through the early '50s is regarded as a benchmark period in American filmmaking, as well as a strong cultural checkpoint for the values of postwar America.
Ddc1 overexpression may lead to a stronger or extended DNA checkpoint response, which may help cope with fork stalling.
This suggests that ESCs may harbor a different mechanism to handle telomere integrity-mediated cellular response since ESCs are characterized by a short G1 and lack a strong cell cycle checkpoint (Orford & Scadden, 2008; Abdelalim, 2013).
