The phrase "a unique sequence in" is correct and usable in written English.
It can be used when referring to a specific arrangement or order of elements that is distinct or one-of-a-kind within a particular context.
Example: "The study revealed a unique sequence in the genetic code that had not been observed before."
Alternatives: "a distinct pattern in" or "an exclusive arrangement in".
This effect was independent of rAAV transduction and specific to the targeting of a unique sequence in human Htt mRNA.
It thus appears that the entire ovalbumin mRNA is primarily transcribed from a unique sequence in the chick genome.
This antibody, which has a unique sequence in its light chain variable region, has been matured to increase the proportion of IgG that enters the cytoplasm (Kim et al., 2016).
Application to 16S rDNA-based detection of bacteria in 144 teeth collected in 86 healthy people yielded a unique sequence in only 14 teeth (9.7%) from 12 individuals (14%).
Primers were selected upstream and downstream of the frameshift in order to amplify a unique sequence in Xff 4834-R genome.
In this study, a GH28-encoding gene (Glyma19g40940) had a unique sequence in R as compared to both S and Williams82 (Table 2).
Sequence variation among domains within single ORFs was also striking, with the great majority representing tracts in which each domain represents a unique sequence (illustrated in Figure 1A).
Recruitment of the Src kinase to the activated form of the platelet-derived growth factor (PDGF) receptor involves recognition of a unique sequence motif in the juxtamembrane region of the receptor by the Src homology 2 (SH2) domain of the enzyme.
Crystal structures of the free and CMP-Kdo-bound forms of KdtA from Aquifex aeolicus reveal details of the CMP-binding site and implicate a unique sequence motif in Kdo binding.
Notably, the index sequence of the human viruses (~68%), which contained the E627K substitution (AAPP KQSRM), was found in the avian host population solely as a unique sequence (~1%) in the Tree sparrow species.
A reason is that only a unique sequence is spotted in the oligonucleotide array.
