The phrase "a stretch of sequence" is correct and usable in written English.
It can be used to refer to a continuous or uninterrupted part of a series or order of items, events, or elements.
Example: "In the analysis of the data, we observed a stretch of sequence that indicated a significant trend over the past year."
Alternatives: "a series of events" or "a range of items".
There's a stretch of sequence which gets copied too many times.
One common feature of these recombinants was that recombination crossover sites contained a stretch of sequence that was identical in both parental molecules.
For each human minimal intron, we randomly selected a position in large introns and intergenic regions and cut a stretch of sequence of equal length as control.
In our supposed preliminary analysis of a reverse vaccinology study, we should recommend, although these two proteins previously seem to be good putative vaccine candidates, not using these proteins for the development of new vaccines as they probably generate antibodies against the human protein with which they share a stretch of sequence.
Gaps in coverage: a stretch of sequence of at least 5 base pairs having zero coverage.
The most straightforward approaches classify promoters by comparing an averaged structural profile for a stretch of sequence to a set threshold.
In these methods, the final sequencing libraries contained a stretch of repetitive sequence introduced by oligo dT) priming.
We also found a stretch of genomic sequence that could be translated into a short CatSper3 fragment sharing sequence similarity with a region in human CatSper3 and the putative chicken CatSper3 fragment (Fig. 4B).
A stretch of poor sequence in the TM4 entry has an additional 18 nucleotides alternately spaced with true sequence.
When two different genes, non-homologous to each other, share a stretch of identical sequence, it begs the question: from which of the two genes did the shared sequence originate?
Allele-specific extension of the immobilized primers took place along a stretch of target sequence with the presence of DNA polymerase and Cy5-labeled dGTP.
