The phrase "at a precise position" is correct and usable in written English.
It can be used when referring to a specific location or point in space or context.
Example: "The satellite is located at a precise position above the equator, allowing for optimal communication coverage."
Alternatives: "at an exact location" or "in a specific spot".
As a result, a true topological link forms at a precise position on the DNA double helix yielding locked, earring-like label.
Also, in tissue engineering, which seeks to repair injured or ill organs, it is necessary to seed living cells at a precise position in three-dimensional (3D) scaffolds to achieve successful production of artificial tissues or organs [5 7].
The requirements on these two parameters are different depending on whether a pinning at a precise position (in the nm range) of the DW is of key importance or whether the displacement of a single straight DW in a given direction over a relatively long distance (in the sub-mm range) is essential.
A control cleavage reaction with ScaI showed that cleavage occurred preferentially at a precise position downstream from the conserved 5'-CA sequence (primary site) matching the cleavage site observed for the standard 3'-processing of a single LTR extremity (band a).
The EJC is a multiprotein complex that is loaded onto mRNA during splicing at a precise position upstream of exon-exon junctions [ 68].
An accepted model for phyllotaxis regulation is that high auxin level accumulation at a precise position in the PZ triggers organ initiation.
To obtain a precise position estimate at reasonable noise levels, the Taylor-series method [51] is commonly employed.
A binary SAM of two thiols (cysteine and cystamine) has been successfully designed over the poly-Au electrode at which a precise positioning of cysteine was achieved, i.e., cysteine was attached to the Au(1 1 1) domains, while cystamine to the Au(1 0 0) and Au(1 1 0) domains.
A confocal pinhole (aperture) is placed at a very precise position in the optical path such that emitted lights coming from the plane of focus will pass through it and enter the photon detector.
Arriving at a precise phylogenetic position for the cambroernids, therefore, has proved difficult.
Instead, we found a conserved internal promoter at the precise position where divergence in disease severity occurs, with the resulting protein product partially rescuing N-terminal truncations.
