The phrase "are encoded by several" is correct and usable in written English.
It can be used when discussing how multiple entities or factors encode information or data.
Example: "The genetic sequences are encoded by several different genes that contribute to the organism's traits."
Alternatives: "are represented by multiple" or "are transmitted by several".
In humans these molecules are encoded by several genes all clustered in the same region on chromosome 6.
They are encoded by several families of human leukocyte antigen (HLA-A, B, and C) genes (Brown et al., 2014).
Group V proteins include the putative chitinase-like IDGFs, which are encoded by several genes in each species, for example, 6, 2 and 2 from D. melanogaster, T. castaneum and An.
NK cell function is facilitated by a repertoire of receptors that are encoded by several gene families, amongst which are the killer immunoglobulin(Ig -like receptor (KIg -likes that areceptored on chromosome 19q13.4 and encode both activating and inhibitory KIR receptors (see review: [5]).
MHC molecules are membrane glycoproteins that are encoded by several closely linked, highly polymorphic genes.
The 20 amino acids are encoded by 4 = 64 nucleotide triplets (codons); some amino acids are encoded by several codons.
Each of these components is encoded by several genes that play subtly distinct roles in signal transduction.
It has four calcium-binding sites (EF-hand domains), is 92% identical to human CaM, and is encoded by several copies in the genome [66].
When proteins encoded by non-significantly differentially-expressed genes were assessed, we found that some of these protein's interacting partners were encoded by several significantly differentially-expressed genes.
Genetic disorders are very heterogeneous and their phenotypes can be encoded by several genetic mechanisms involving more than one gene.
