The phrase "a sequence appeared" is correct and usable in written English.
It can be used when describing the emergence or occurrence of a series of events, items, or elements in a particular context.
Example: "As the experiment progressed, a sequence appeared that indicated a clear pattern in the data."
Alternatives: "a series emerged" or "a pattern manifested".
If a sequence appeared in a cluster with homogeneously named, fully identified sequences, it was assigned to that species if this was not contradicted by the phylogenetic analyses.
If a sequence appeared in at least 2 individuals or was found in 2 independent PCRs from a single individual, we recognized it as an allele.
The observation of end variants has literary precedence (see [32]). 5. Occurrence refers to the number of times a sequence appeared during our cloning and sequencing.
All approaches require a careful choice of characteristics to use as discriminators of whether a sequence appears to be typical or not for its genome.
When a sequence appears in different positions in the genome, the minimal value for each of the four distances is used.
For sequence-based analyses, sensitivity depends on the frequency with which a sequence appears in a fragment library, the number of clones produced, the efficiency of known virus subtraction (if applied), and the number of different clones sequenced.
A combination of a sequence editor and tree visualisation tool in one program is particularly handy at the stage of preliminary evaluation and checking of the datasets, as oddities in the data, such as misalignment or sequencing errors make a sequence appear more diverged, which is easily identifiable from the inspection of a gene tree and can be quickly fixed within ProSeq3.
A custom script was used to identify all unique reads (contigs) and generate a counts matrix detailing how many instances a particular sequence appeared in each bar-coded sample.
Following the appearance of six hyaluronidase-like sequences in the zebra fish, a seventh sequence appeared in the mouse genome, with the unfortunate appellation of Hyal5 (Kim et al. 2005).
Speaking in his soft English accent, he ran through some of the engine's bag of tricks, such as entering strings of Gs, Cs, As, and Ts to obtain detailed data about the genes in which a DNA sequence appeared.
If an unidentified sequence appeared as sister taxon to a fully identified species in the phylogenetic analysis and had at least 80% sequence similarity in ITS2, it was denoted as aff. of that species (e.g. I. aff. boltonii).
