The phrase "a perfect complementarity between" is correct and usable in written English.
It can be used to describe a situation where two or more elements enhance or complete each other in an ideal way.
Example: "The collaboration resulted in a perfect complementarity between the two departments, leading to increased efficiency and innovation."
Alternatives: "an ideal synergy between" or "a flawless harmony between".
The slicer activity of Argonaute requires a perfect complementarity around the cleavage site of the guide-target duplex [ 25].
Masking uses oligonucleotides that modulate a specific miRNA target, since they display a perfect complementarity to the target miR [ 58, 63].
In metazoan, the situation is more complex since a perfect complementarity is not necessary for a miRNA to recognize its targets.
However, the strong RBS in the 5′ UTR of gfp in pXG-1 (Urban and Vogel, 2007) shows a perfect complementarity to part of the conserved Yfr1 motif.
Importantly, one of the genes was integrin α5 (ITG α5), whose 3′-UTR sequence had a perfect complementarity with the seed sequence of miR-205.
A perfect, or near perfect, complementarity between an miRNA and its target mRNA, which is a peculiar feature of plant miRNAs, provides a powerful tool for the identification of target genes through BLAST analysis of mature miRNA sequences against EST sequences.
The perfect or near perfect complementarity between a miRNA and its target mRNA, that is a peculiar feature of plant miRNAs, gives a powerful tool for the identification of target genes through BLAST analysis of miRNA mature sequences vs EST/genomic sequences.
The miRNA-target recognition is mainly due to the perfect complementarity between a short 7 8 nt stretch at 5' end of the miRNA molecule (miRNA seed) and the corresponding stretch on the 3'UTR of the target gene (seed match).
The -en option defines the minimum free energy threshold for a miRNA-target pairing, while the -strict option demands perfect complementarity between the miRNA seed region and the target.
There was perfect complementarity between the seed region (the core sequence that encompasses the first 2 8 bases of the mature miRNA) and the putative target sequence.
