The phrase "a perfect complementarity to" is correct and usable in written English.
It can be used when describing how two things enhance or complete each other in a harmonious way.
Example: "The new software provides a perfect complementarity to our existing systems, improving overall efficiency."
Alternatives: "an ideal match for" or "a perfect addition to".
Seed region composition was defined as follows: "8mer" have an 'A' at position 1 and perfect complimentary from positions 2 8 of the mature miRNA; "7mer-m8" have perfect complementarity from positions 2 8 of the mature miRNA; and "7mer-1A" hane An 'at at position 1 and perfect complementarity to positions 2 7 of the mature miRNA.
The miR-145 pMIR-REPORT luciferase reporter vector was cloned by inserting a oligo with perfect complementarity to mature miR-145 into the HindII/SpeI site of pMIR-REPORT Luciferase vector (AM5795, Applied Biosystems).
The miR-143 luciferase reporter vector was cloned by inserting a site with perfect complementarity to miR-143 into HindIII/SpeI sites of pMIR-REPORT (AM5795, Applied Biosystems).
Silencing of the piRNA sensor is established through an endogenous piRNA (21-UR-1) with perfect complementarity to a corresponding sequence in the piRNA sensor (Bagijn et al., 2012).
We designed a modified U1snRNA with perfect complementarity to the authentic F9 exon 2 5′ss (U1Figt) (Fig. 3A), which therefore has a single mismatch for each mutant.
Three unidirectionally cloned ESTs (accessions CD585878, CD585963 and CD596001) were all revealed upon sequencing to correspond to a 914 nucleotide long cDNA sharing perfect complementarity to nucleotides 2701 3614 of the grna cDNA (Additional File 11, panel A).
Unexpectedly, we were unable to identify by BLAST a single target transcript with perfect complementarity to any of our recovered shRNA sequences.
The 10 nt motif returned by MEME included a 7 nt stretch with perfect complementarity to positions 2 8 in miR-124.
This prompted us to conjecture that a candidate dsRNA (dsP21-397) with perfect complementarity to the miR-1180-5p target site of p21 promoter may also trigger p21 expression.
