This case-sensitive code system http://hl7.org/fhir/uv/cg-incubator/CodeSystem/moleculardefinition-type defines the following codes:

CodeDisplayDefinition
genomic-dna Genomic DNADNA that encodes, or is derived from, the genomic DNA of an organism.
cdna cDNAA DNA molecule synthesized from a mature mRNA template by reverse transcriptase.
single-stranded-cdna Single-stranded cDNAA cDNA molecule that is single-stranded.
double-stranded-cdna Double-stranded cDNAA cDNA molecule that is double-stranded.
mitochondrial-dna Mitochondrial DNAA DNA sequence of mitochondrial origin.
mrna mRNAMessenger RNA; a mature transcript that is translated into protein.
rrna rRNARibosomal RNA; a structural component of the ribosome.
trna tRNATransfer RNA; an adaptor molecule for translation.
snrna snRNASmall nuclear RNA; involved in pre-mRNA splicing.
snorna snoRNASmall nucleolar RNA; involved in rRNA modification.
mirna miRNAMicroRNA; a small regulatory RNA that silences gene expression.
sirna siRNASmall interfering RNA; mediates RNA interference.
lncrna lncRNALong non-coding RNA; an ncRNA of 200 nucleotides or more with regulatory roles.
antisense-rna Antisense RNARNA transcribed from the antisense strand of a gene.
ncrna ncRNANon-coding RNA; a mature transcript that is not translated into protein.
pirna piRNAPIWI-interacting RNA; involved in transposon silencing in germline cells.
