The phrase "are conserved in a" is correct and usable in written English.
It can be used in scientific or technical contexts to describe the preservation of certain properties or quantities within a system or process.
Example: "In this experiment, the energy and momentum are conserved in a closed system, demonstrating the principles of physics."
Alternatives: "are maintained in a" or "are preserved in a".
Persistent genes, although not ubiquitous, are conserved in a majority of genomes, tend to be expressed at high levels, and are frequently located on the leading DNA strand.
The first law of thermodynamics has provided the concept of internal energy and enthalpy, which are conserved in a physicochemical system.
Our results suggested that these residues, which are conserved in a paralog-specific manner, confer specificity by recognizing a sequence-dependent DNA structure instead of reading a specific DNA sequence.
In this method some of the most important statistical moments (e.g., concentration of the main chemical species and enthalpy) are conserved exactly, while other moments are conserved in a statistical sense.
Energy, momentum and the like are conserved in a closed system; but the claim that the material universe is in fact a closed system is not part of classical physics; it is another metaphysical or theological add-on.
The functions of core members of the σE regulon are conserved in a number of bacterial species [9].
Moreover, several genes (patU, hetR and hetF) that are required for heterocyst maturation and N2 fixation are conserved in A. platensis, although no nitrogenase genes were detected; this suggests that heterocyst formation could be developmentally coupled with trichome formation.
To examine whether these factors involved in 3′-end-processing are conserved in A. oryzae, we searched for homologous proteins of 20 yeast polyadenylation factors in the A. oryzae genome (Table 3).
Both ε and B are conserved in an ideal optical system but are degraded by Coulomb repulsion between electrons, which reduces B and increases ε.
A follow-up to QRNA by Bernardo et al. is ddbRNA [7], a program for finding all potential stems that are conserved in an alignment of multiple sequences.
The rsrA allele is located in a syntenic region in the genomes of Aspergillus spp. and its function is conserved in A. nidulans, A. flavus and A. fumigatus.
