The phrase "a sequence appears" is correct and usable in written English.
It can be used when discussing patterns, trends, or occurrences in data, literature, or any context where sequences are relevant.
Example: "In the analysis of the data, a sequence appears that suggests a correlation between the variables."
Alternatives: "a pattern emerges" or "a series is observed."
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.
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.
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.
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.
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.
In this task, the agent is to make a response when a target sequence appears, where the target sequence depends on whether a 1 or a 2 most recently occurred in the string.
The combination of a conserved secondary structure with a variable sequence appears to be a major benefit of using ITS2 [ 30].
Motivation: Converting a pyrosequencing signal into a nucleotide sequence appears highly challenging when signal intensities are low (unitary peak heights ) or when complex signals are produced by several target amplicons.
To avoid HOEs, PSI-Search always uses the alignment boundary information from the first significant alignment in which a library sequence appears.
