Duplications occurred predominantly (73.6%) within the complex region, suggesting that the recombination between duplicated segments within the region may also be frequent in somatic cells.
Let us consider an undirected graph in which nodes represent the segments (tree leaves) and edge lengths the evolutionary distances between pairs of segments within the underlying tree (Fig. 2b).
The confocal microscopy revealed the collapsed capsule interiors, which occurred most probably due to hydrogen bonding between PMAA and PVPON segments within the hydrogel walls and also through the capsule interior.
>> Before interpretation of those findings is presented, it is necessary to discuss one additional issue, i.e. possible effects of the presence or absence and structure of crystalline phase and of interactions between rigid and soft segments within the crystalline and amorphous phases, on the measured contact angle values and on SFE parameters.
Protonation of the PAA carboxylic groups with decreasing pH promoted hydrogen bonding between the PAA and PVP segments within the crosslinked structure and caused the gel to collapse.
Rather, the model displayed clear steric clashes between the LP2 Rpn6-N conformandon and segments within the base ATPase subunits Rpt3, Rpt4, and Rpt6.
Most known AICEs subsist in their host genome by integration in the 3' end of a tRNA gene by site-specific recombination between two short identical sequences (att identity segments) within the attachment sites located on the genome (attB) and the AICE (attP), respectively [ 69].
