The phrase "a few sequences of" is correct and usable in written English.
It can be used when referring to a small number of ordered sets or series of items, events, or elements.
Example: "In the experiment, we analyzed a few sequences of DNA to identify genetic variations."
Alternatives: "several series of" or "a couple of patterns of".
Some of the primers that have been used are based on a few sequences of a variable region in the SSU rRNA gene.
Jolson had sung -- and, more important, breezily gabbed -- in only a few sequences of that otherwise silent movie, but sound was knocking insistently at cinema's door, and ultimately nothing would keep it out.
Simon Wann-Hobson, AIDSIDS researcher at the Pasteur Institute in Paris, cautions, however, that because only a few sequences of chimpanzee SIV are available for comparison, "it's too close a call".
Most multiple sequence alignment programs use heuristic methods rather than global optimization because identifying the optimal alignment between more than a few sequences of moderate length is prohibitively computationally expensive.
What initially feels like a fiddly control scheme – it takes three (albeit quick) interactions to call your horse, for example: hold the shoulder button, use the right stick to select the correct option, and click it to confirm – comes into its own after a few sequences of stealthily skulking around enemy outposts.
A few sequences of Serratia differed clearly from the others (by 1.4%), indicating two separate bacterial lineages.
Sequences which covered more than 70% overlap between forward and reverse sequences were considered (except a few sequence of matK where coverage was less than 50%).
The biological meaning of most of the other clusters remains however still speculative, since they were defined on the basis of a few sequences out of each library.
The sequencing effort of the GTDF increased the number of Fagaceae cDNAs available in GenBank from a few sequences to hundreds of thousands of sequences for each of the species studied.
In 1984, when Charles Stewart returned from Africa with harrowing film of the Ethiopian famine, James sat in the editing suite one day to switch around a few sequences in Seeds of Despair that made the pictures even more powerful.
For a few sequences, manual assembly of scaffolded sequences was required to obtain complete coding regions.
