ncRNA lncRNA kareneilbeck sequence Updated the definition of lncRNA (SO:0001877) from "A non-coding RNA over 200nucleotides in length." to "A non-coding RNA generally longer than 200 nucleotides that cannot be classified as any other ncRNA subtype. Similar to mRNAs, lncRNAs are mainly transcribed by RNA polymerase II, are often capped by 7-methyl guanosine at their 5' ends, polyadenylated at their 3' ends and may be spliced." See GitHub Issue #575 lncRNA_transcript A non-coding RNA generally longer than 200 nucleotides that cannot be classified as any other ncRNA subtype. Similar to mRNAs, lncRNAs are mainly transcribed by RNA polymerase II, are often capped by 7-methyl guanosine at their 5' ends, polyadenylated at their 3' ends and may be spliced.
