The phrase "are maintained during evolution" is correct and usable in written English.
It can be used in contexts discussing biological processes, changes over time, or the stability of certain traits or characteristics throughout evolutionary history.
Example: "Certain genetic traits are maintained during evolution, allowing species to adapt to their environments."
Alternatives: "are preserved throughout evolution" or "are sustained during evolutionary processes."
The assumption behind the estimation of insertion ratio (equation (5)) is that the order of the exons within each gene is maintained during evolution.
The majority of spliceosomal introns in vertebrates may be maintained during evolution not because of potential functions, but because of their splicing mechanism (i.e., exon definition).
An intriguing question is whether HGT is maintained during evolution of prokaryotes owing to its adaptive value or is a byproduct of selection driven by other factors such as consumption of extracellular DNA (eDNA) as a nutrient.
Thus, a new concept was discussed on how the absence of some tRNA synthetase has been maintained during evolution of some intracellular bacterial pathogens to gain protein diversity in the population and ensure better adaptation to stress.
Thus, the low DNA-binding specificity of AdpA has been maintained during evolution, suggesting that this atypical characteristic of AdpA as a bacterial transcription factor should be very important for the biology of Streptomyces.
However, it is unclear whether other insect species and Daphnia contain the miR genes at the same genomic locations and how long their target sites have been maintained during evolution.
The positions and lengths of exons are quite similar for all genes suggesting that the structure of the ancestral GS gene has been maintained during evolution with some modifications, such as the presence of a plastid targeting sequence in the first exon of GS2 and minor changes in some other exons of GS1 genes.
A reasonable explanation for the double signal is that large duplicated segments in allotetraploid cotton are maintained during long-term evolution after polyploidy formation.
