The phrase "are generally permissive" is correct and usable in written English.
It can be used to describe rules, policies, or attitudes that allow for flexibility or leniency in certain situations.
Example: "The new guidelines for the project are generally permissive, allowing team members to explore creative solutions."
Alternatives: "tend to be lenient" or "are mostly flexible."
They deal mainly with local officials, who are generally permissive (energy, after all, is a well-loved commodity in Texas).
This suggests that boundaries between CIDs, which are generally associated with highly open and active promoters, may reflect chromatin domains that are generally permissive for transcription.
In mammals the TAP molecules are generally permissive in the peptides they pump into the ER and it is the class I molecules that are selective in the peptide they will bind.
As a bleeding-heart liberal, I'm generally permissive when it comes to cornball softness.
The genome of eukaryotic cells is organised into euchromatin, which is generally permissive for gene activation, and heterochromatin, which is largely gene-poor or transcriptionally silenced.
All other mice in this study carried an Xpr1 s v x haplotype which is generally permissive to exogenous MLV infection.
Yet, it may be that they are narrowly optimized to express R11C05-LexA, rathan than being generally permissive for expression of various transgenes.
Finally, the genome appears to be generally permissive for transvection (Chen et al. 2002), so it is likely that many more genes undergo transvection than those that have been identified based on intragenic complementation.
However, previous work from others indicates that the genome is generally permissive for transvection (Chen et al. 2002), and our results with attP40 and attP2 are consistent with that view.
Although the precise molecular function of H3K4me2/3 in vivo and its contribution to gene expression remain poorly defined, these marks are generally considered permissive to active transcription.
That α ^ was predominantly less than 1, indicates that the amino acid exchanges involving the MAA are generally less permissive than the common nonsynonymous substitution rate (represented by ω) affecting all amino acids.
