Both haploid and diploid ccr4Δ strains are sensitive to S phase specific DNA damaging agents such as HU, indicating that CCR4 haploid and diploid mutants share a common checkpoint repair defect that extends into S phase.
Bright yellow Hezbollah flags flew over all the old South Lebanon Army and Israeli strongholds and gun positions, but there was no sign in the streets of armed militiamen or the once-common checkpoints.
Corruption is common at checkpoints and border crossings, and the trade in ape meat is largely underground.
In the studies performed by Lambert et al, they observed that Cds1 kinase activity was upregulated in response to nitrogen mustard treatment to the same level observed with the common replication checkpoint inducing agent, HU [37].
The most common use of checkpoints is when a task execution fails.
RPA-single-stranded DNA complexes are common intermediates in checkpoint responses and DNA repair reactions [39].
Single stranded DNA (ssDNA) is a useful common DNA damage checkpoint signal as it is formed during nucleotide and base excision repair, during resection at the ends of double stranded DNA breaks and at stalled replication forks [2].
Ennio Prosperi (CNR, Pavia, Italy) discussed the common feature of checkpoint and DNA factors at DNA damage sites.
Security checkpoints are common, and also efficient.
Because Las Cruces is so close to Mexico, Border Patrol checkpoints are common along the highways leading in and out of town.
