Nucleation-bulge sites consist of 8 nt motifs paired to positions 2 8 of their cognate miRNA seed, with the nucleotide opposing position 6 protruding as a bulge but sharing Watson-Crick complementarity to miRNA position 6.
Let p S, w) be the position paired to the position w in the RNA structure S ∈ C(λ i -1), or 0 if position w is unpaired.
Positive reactions produced a 606 base pair (bp) fragment, corresponding to position 55 – 660 of the nucleoprotein gene.
The solution containing GeNWs was dropped while the centrally located metal pairs were ac-biased to position the GeNWs in the designated location.
At the same time, protein structure alignment is a very difficult problem, due to an infinite number of possible ways to position a pair of proteins in the three-dimensional space.
Formally, a pseudoknot occurs if there are two base pairs with indices i paired to j and k paired to l, with positions i < k < j < l.
This result suggests that the fluctuation of the overall tRNA abundance pairing to each codon position along this nsp1 α might not regulate the formation of the specific folding units but decrease the scanning speed of ribosomes in the pig cells.
The best characterized features determining the targets of a specific miRNA are the conserved Watson-Crick pairing to the 5' region (positions 2 7) of the miRNA, which are the so-called "seed pairing rules" [ 3, 10- 13].
In the study, no linkage between the fluctuation of the overall tRNA abundance pairing to the codon positions along the nsp1 α gene and the specific folding units might suggest that the process of translation fine-tunes is not performed by variation of translation speed for each codon position along the nsp1 α.
A direct repeat of three base pairs, corresponding to positions 33, 34 and 35 of each broken REP sequence, is generated and appears at both extremes of the IS element [see Additional file 1].
