The phrase "a sequence less than" is correct and usable in written English.
It can be used in mathematical or comparative contexts to describe a sequence that has a value or length that is smaller than another reference point.
Example: "In this problem, we are looking for a sequence less than five terms long."
Alternatives: "a series shorter than" or "a progression fewer than".
The new reactions produced a double sequence less than 80 bases from the end of the PCR fragment (P0 site).
The average percent of exonic sequence in these trials was 23.4%, and only 15 trials produced a percent exonic sequence less than or equal to 3.3%, yielding an empirical P-value of 0.015.
Another important fact to stress is that IPknot can run quite fast even on a relatively long sequence less than one thousand bases.
We next combined HSVs co-locating within a region of gene sequence less than the 51 base pair length of an individual sequence read to produce haplotypes.
Homoeologous sequence variants (HSVs) co-locating within a region of gene sequence less than the 51 base pair sequence read length were combined to produce haplotypes.
A domain bigram, consistent with the definition of domain combination in SUPERFAMILY, is defined as an adjacent domain pair with gap sequence less than 30 amino acids.
After discarding 3' adapter deletions, insertion deletions, 5' adapter contaminants, poly-A sequences and sequences less than 18 nt from the high-quality reads, 17,557,485, 19,398,402 and 17,764,475 clean reads were used for further analysis.
De novo transcriptomes to date keep in a small amount of sequencing less than 6 Gb of total sequence data, resulting in contigs or scaffolds with mean length less than 600 bp [22], [23], [24].
They were not automatically selected by our initial profile-profile procedure because their HMM profile was built from a too limited number of sequences (less than 5 homologous sequences in the nr database retrieved at the PSI-Blast stage).
