Abstract
—The term non-coding RNA (ncRNA) is widely used to refer to RNA that fails to encode a protein; nevertheless, this does not mean that such RNAs lack information or function. Recent evidence suggests that most of the genomes of mammals and other complex organisms are transcribed into ncRNAs, several of which are alternatively spliced and/or managed into smaller products. Large ncRNAs, like ribosomal RNAs (rRNAs), which are involved in the synthesis of proteins, and small ncRNAs, like small nucleolus RNAs (snoRNAs) for RNA modifications, small nuclear RNAs (snRNAs) for RNA splicing, and transfer-RNAs (tRNAs) for transporting amino acids, have been extensively investigated in the past fifty years since the beginnings of molecular biology. These ncRNAs may be considered 'constitutive' because they are abundant and ubiquitously expressed in all cell types and play critical roles in the organism. In conclusion, a growing number of particular non-coding RNAs (ncRNA) are important modulators of numerous biological processes, such as chromatin remodeling, epigenetic changes, apoptosis, control of the cell cycle, and gene expression. Furthermore, the reason for the irregular relationship between an organism's complexity and this class might additionally encompass the telomere complex-associated guide RNA, which is essential for the end formation as well as preservation of chromosomes in normal proliferating.
