The phrase "are annotated with a" is correct and usable in written English.
It can be used when describing items or documents that have been marked or explained with additional information.
Example: "The research papers are annotated with a detailed summary of their findings for easier understanding."
Alternatives: "are marked with a" or "are accompanied by a".
For example, if a sufficient number of genes from a set are annotated with a common GO term, the annotation is considered to be 'enriched' and, therefore, the genes are deemed functionally coherent.
Proteins are annotated with a detailed description of protein families, biological process and related diseases.
To this end, the ImmPort has developed a set of data upload templates (http://www.immport.org/immport-open/public/home/dataTemplates) through which key elements of biomedical research data are annotated with a consistent set of descriptors.
Forty-nine of the indica eQTLs are annotated with a gene function and the others are 36 unknown genes, 9 hypothetical proteins, and 10 transposons/retro-transposons.
PubMed records that are annotated with a given MeSH chemical concept are then associated with the PubChem Compound record linked to the MeSH chemical concept.
Of 490 japonica eQTLs, 181 entries are annotated with a gene function; the remainder are 256 unknown (expressed) genes, 9 hypothetical proteins, and 44 transposons/retro-transposons.
Of those matched genes the % identical subsets are annotated with an identical annotation.
miRNAs with nearly identical sequences except for one or two nucleotides are annotated with an additional lower case letter.
Of these 900 proteins, 664 could already be annotated with a GO biological process term using annotation from GOA (Camon et al., 2004) and allowing all evidence types.
Each plot is annotated with a label and scale bar, and the position of sources detected by 2MASS are marked.
