A Cambridge study found that elephants can learn to coordinate with a partner on a task that required the pair to simultaneously pull two ends of the same rope in order to obtain a reward.
Meiotic recombination requires the pairing of homologous chromosomes before exchange.
Moreover, in this search for homologs belonging to syntenic blocks, we further required that the pair of aligned amino acid sequences extend at least 80% of the length of the shorter matching protein.
To study whether co-evolution requires the pairing, in terms of pollination effectiveness, of moth and plant species, we set pXA = pYB = 0.25+δ and pXB = pYA = 0.25 δ and run the simulations for different values of δ.
However, it has been reported that yeast NHEJ Pol4 is required for the pairing of 3′ overhangs (Daley et al., 2005b; Daley and Wilson, 2008), suggesting that lower eukaryotes may also require NHEJ polymerases to promote break synapsis under certain circumstances, possibly because they lack additional synapsis factors.
Since mature miRNA contains only 19-25 nucleotides and detective probes on the array carrier require the complementary pairing of at least ∼20 base pairs, the full-length sequence of each mature miRNA must inherently be included in the probes.
when ρ = 0.5 and δ = 1, to ensure M is not less than the minimum number of required samples to achieve the pair of target probabilities ( left({overline{P}}_d,{overline{P}}_fright) ).
Despite these favorable attributes, these polypeptides are notoriously difficult to produce recombinantly in significant quantity due to their structure which requires the correct pairing of multiple disulfide bonds for biological activity.
Nonetheless, these polypeptides are notoriously difficult to produce recombinantly due to their particular structure requiring the correct pairing of multiple disulfide bonds for biological activity.
Although precise mechanistic details remain to be determined, our model suggests that reorientation would require the re-pairing of the Lys126 Glu400 salt bridge between H4 and H10 at an early stage.
