Sentence examples for base combination at the from inspiring English sources

The approach we have taken to model context-dependent evolution at the third codon position selects one of 16 models using the neighbouring base combination at the start of each branch, which means that for a given site the context might change at each internal node of the underlying phylogenetic tree.

Contrary to the original context-dependent model developed for non-coding sequences [ 13], the evolution of the third codon position could be allowed to depend upon the neighbouring base combination at both the start and the end of each branch.

The specific base combination CAG (repeated at least 7 times) is found in 1815 genes, leading to conceptual translations into homopolymeric amino acid repeats (HAARs) of alanine (A), glutamine (Q) or serine (S) in 1781 (30%) proteins.

The DSSC based on a TiO2/TNT combination at the optimal weight percentage (10 wt.% TNT) showed better photovoltaic performance than the cell made purely of TiO2 nanoparticles.

Regardless of the base pair combination at these three sites, this infection represented a mixed infection of one Plasmodium and one Haemoproteus infection within the same host (Table S4).

But this fact does not contradicts Shepherd's observation since he himself stated that ".counts of certain correlated base combinations are only given at separation intervals of three bases and are zero at all other separations (i.e. the correlation signal amplitude is a maximum and the background is zero)".

This method recommends the constant-ratio drug combinations (at the (IC50 1/ IC50 2) based on the notion that the mixture can be deemed as a third drug.

Based on SINE occupancy there can only be eight combinations at the three loci (i.e. 2).

Different combinations at the RVDs allow for recognition of a single base.

For combinations involving Watson-Crick base pairs at the ligation junction, yields of full-length ligated product ranged from 13 to 89% following the 6 h reactions (Fig. 4B).

Recognition of the set of tRNAs that would be required for the large irregular shaped codon blocks in Figure 6 would either require a sophisticated synthetase that distinguished complex combinations of bases at the three anticodon positions, or would require separate synthetases for the same amino acid that recognized simpler subsets of anticodons.
