LncRNAs initially were considered a

LncRNAs initially were considered as byproduct of transcription of
RNA polymerase II. They had been described as “dark matter” and did
not have a biological function. However, whole genome transcriptomic
analyses have identified large numbers of dynamically expressed long
non-coding RNAs, many of which are involved in a variety of biological
functions.
