An organism's transcriptome is the entirety of its RNA. After identifying 11,655 non-protein-coding RNAs in 2002, the FANTOM consortium concluded that the major component of the transcriptome is a Non-coding RNA.
The Complexity of the Transcriptome
Molecular biologists originally believed that only one strand (the "sense" strand) of the DNA molecule contains information that is transcribed into RNA. The other, "antisense" strand, was expected to function only in DNA replication. However, ENCODE project and FANTOM consortium showed that this expectation has not come true and that RNAs are transcribed from both strands of DNA, while the "antisense" strand is a major component of transcriptome.
