As a result, the smaller and larger (SSC and LSC, respectively) regions between the Cairn's intermediates, would be left single-stranded, one half for one parental strand and the other half for the other parental strand (Step 4 of Figure 10A).
At this step, if one assumes equal rates of replication forks on both parental strands, one half of the region between A2 and A1 would be left single-stranded for one parental strand, and the other half for the second parental strand, resulting in short gradients in times that the DNA spends single-stranded, from the origins towards the center of the region (Step 1 of Figure 10A).
The old doubts about female competitiveness derived partly from an evolutionary analysis of the reproductive odds in ancient polygynous societies in which some men were left single because dominant males had multiple wives.
After the pairing off was finished, women who were left single built a large ceremonial bonfire and burned images of men who'd hurt them.
In short, the H-strand is left single-stranded for an extended period and subject to spontaneous deamination of A and C [11], [12] to G and U.
These gradients increase bi-directionally from the center of each region towards the respective ends, suggesting that both the strands were left single-stranded during replication.
As a result of this mechanism, half of each displaced parental strand (from either origin until the center of two origins) is left single-stranded on both sides of the pair of inverted repeats.
One could, therefore, explore the presence of A → G gradients in chloroplast genome regions between mapped replication origins and infer from the direction of these gradients, the direction in which the DNA is left single-stranded during replication.
Single-stranded regions of the genome and gradients in time that these regions are left single-stranded, as revealed by our nucleotide composition analyses, appear to converge with the original bi-directional dual displacement loop model and restore evidence for its existence as the primary mechanism.
That national bias is one reason gay people fight for the right to marry, but now some researchers are concerned that the marriage equality movement is leaving single people behind.
With each blitz, Sehorn could easily be left in single coverage.
