The phrase "inverse orientation" is correct and can be used in written English.
It refers to something that is the opposite or reverse of the usual or expected orientation. Example: The map was printed with an inverse orientation, making it difficult to read and follow the directions properly.
This inversion event explains the inverse orientation of the CτA-4 sequence in IGH-A.
The product was digested with SalI and XbaI and inserted in the inverse orientation into the XbaI and XhoI sites of the FLEX-pACP plasmid.
However in fish genomes, this locus contains two additional conserved markers ANKRD5 and EMILIN1 (Table S4) flanking in inverse orientation.
Although the inverse orientation has been assumed to be typical of all insect ORs, this remains to be formally demonstrated.
When these recognition sites are placed to the far 5' and 3' end of any DNA fragment in inverse orientation, they are removed in the cleavage process, allowing two DNA fragments flanked by compatible sequence overhangs to be ligated seamlessly.
In fish, the marker sets were not totally conserved: on one side, the CITED4 gene was present, on the other side, two additional flanking genes MANEAL and SF3A3 (Table S4) were present in inverse orientation to the conserved LIN28.
Seventeen percent of the clones genetically positioned by SNPs were oriented by virtue of informative intra-clone recombination events in the cross; 13% of these had relative inverse orientations within the genetic and physical maps.
Second, to our knowledge the 5S genes of angiosperms are exclusively encoded by the opposite DNA strand to the 35S genes while in gymnosperms both direct and inverse orientations occur.
Intrachromosomal and interchromosomal identical repeat pairs with a length of at least 300 bp in either direct or inverse orientations were identified in the human genome reference assembly of the NCBI build 36.2 using the programs Reputer version 3.0 and MUMmer version 3.19.
In 2010, another question was raised regarding the inverse orientations of the Phi29 motor channel and dsDNA helices [ 52], which further questioned the involvement of rotational motion, since the rotation mechanism of dsDNA as a bolt threading onto a motor channel as a nut requires that the threads of the bolt and the nut have the same directionality.
With respect to intrachromosomal duplicates, paralogs in inverse transcriptional orientation are equally frequent as paralogs in direct orientation.
