Sentence examples for shift in base from inspiring English sources

The shift in base level may be related to megamonsoons during the Carnian-Raleigh of Late Triassic Epoch (Shi et al. 2010) in the Middle and Upper Yangtze regions of the Sichuan Basin.

Specifically, slippage of the (AG 4 repeat in CAN1 during annealing to the corresponding (AG 3 repeat in LYP1 may have led to looping out of a single repeat unit in CAN1 (Figure 6 F) or, more likely, a shift in base pairing (Figure 6 G).

The shift in base substitution results in a significant detectable shift in base composition between N2 (35.44%GC) and CB4856 37.77%GCCB4856 37.77%GC

The dramatic shift in base composition in coding sequences might very well reflect novel codon preferences in this species group, as suggested by others [ 27].

The documented shift in base composition of intronic sequences is similar between short and long introns, and appears to be minor.

Temporal shifts in base profile, nevertheless, affected the tripartite division of the LST, systems tract developed during relative sea level lowstand.

Lucas [3], [30] argued that these cycles instead represented shifts in base level driven by eustatic sea level change, while Kraus and Middleton [83] and Cleveland et al. [81] suggested that they were driven by tectonic uplift.

To check for possible shifts in base composition among species, we calculated the base composition for each species using PAUP 4.0b10 [ 91].

According to Phillips and Penny [ 23], the Marsupionta clade can be explained by parallel shifts in base frequencies in mitochondrial genomes of Monotremata and Marsupialia.

Concerning rRNA-genes of arthropods, shifts in base composition are mentioned for Diptera, Diplura, Protura and Symphyla [ 1, 23, 34, 44, 73, 85].

2. The nucleotide frequency distribution across all haplotypes did not reveal any shifts in base composition, so as to hint at a pseudogenization (i.e. the process leading to loss of function of a locus following duplication or transposition), which is mostly expected for coding loci (graph not shown).
