disposition gene disposition Yongqun He a disposition that a gene can be used as a blueprint for generating a new form of product such as protein. WEB: http://www.ncbi.nlm.nih.gov/IEB/ToolBox/CPP_DOC/lxr/source/src/objects/entrezgene/entrezgene.asn YH: According to NCBI Gene project, there are two gene types: unknown (0) , tRNA (1) , rRNA (2) , snRNA (3) , scRNA (4) , snoRNA (5) , protein-coding (6) , pseudo (7) , transposon (8) , miscRNA (9) , ncRNA (10) , other (255). Therefore, we have generated corresponding gene dispositions. Note that we don't use the term "gene type" here to differentiate the meanings of "type" and "disposition".
