It is immensely illuminating on the reach of current cosmological theories but one persistent strand is bound to baffle many readers.
Since his leadership began he has tempered his Europhobia, but there is a persistent strand of leftish Euroscepticism that has been given added passion by the impact of austerity in the eurozone.
Interaction of Lula induction with the two early pathways was especially interesting, since, as we have shown, Lula's induction requires RecA filamentation in response to DNA damage, and RecA filamentation on ssDNA is licensed by the early activities — RecBCD acting on double-strand ends or RecFOR acting on persistent single-strand gaps [32], [33].
The latter resulted in persistent positive-strand viral RNA and accumulation of replication intermediates, negative-strand viral RNA, in the infected cells, suggesting that the internalized viruses have undergone replication.
If Swift is keen to put the persistent latter strand to rest, an appearance on the 1989 World Tour stage would cement her relationship with Harris at least to the level that it did with Joan Baez and Chris Rock.
Consistent with the recF interactions, Lula prophage greatly increases the UV sensitivity of the recG mutant (Fig. 5F), again suggesting independence of Lula's induction of the repair of persistent single-strand gaps.
To gain new insight into the impact of the deletion of ERCC1, Msh2 or p53 on the integrity of DNA in germ cells we examined whether persistent DNA strand breaks were present in pachytene spermatocytes by performing immunostaining for γH2AX.
In contrast to the recBCD result, the recF-defective Lula lysogen is significantly more sensitive to UV than either wild type Lula lysogen or the recF non-lysogen (Fig. 5E), suggesting that Lula is induced by UV independently of the RecFOR pathway that assembles RecA filaments on the persistent single-strand gaps.
This was consistent with the highest amount of persistent DNA strand breaks in the spleen of 7 days old mice.
Depletion of EXOG in human cell lines results in persistent single-strand breaks in mtDNA, increased mitochondrial dysfunction, and increased apoptosis (Tann et al. 2011).
