RNAs such as microRNAs, siRNAs, piRNAs, snoRNAs, snRNAs, exRNAs, scaRNAs and the long ncRNAs such as Xist and HOTAIR. The number of non-coding RNAs within...

molecular genetics, an untranslated region (or UTR) refers to either of two sections, one on each side of a coding sequence on a strand of mRNA. If it is found...

The 5′ untranslated region (also known as 5′ UTR, leader sequence, transcript leader, or leader RNA) is the region of a messenger RNA (mRNA) that is directly...

In molecular genetics, the three prime untranslated region (3′-UTR) is the section of messenger RNA (mRNA) that immediately follows the translation termination...

in the mature mRNA. Several roles in gene expression have been attributed to the untranslated regions, including mRNA stability, mRNA localization, and...

this is not the biological role of asd RNAs. First, in some cases, the asd RNA is not in the 5' untranslated region of any annotated gene. Second, in...

designed mRNA. The in vitro transcribed mRNA has the same structural components as natural mRNA in eukaryotic cells. It has a 5' cap, a 5'-untranslated region...

MicroRNA (miRNA) are small, single-stranded, non-coding RNA molecules containing 21 to 23 nucleotides. Found in plants, animals and some viruses, miRNAs are...

mRNA can exit the nucleus and find the ribosome. It is added at a polyadenylation site in the 3' untranslated region of the mRNA, cleaving the mRNA in...

cells by which an RNA primary transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can...

transcribed together into an mRNA strand and either translated together in the cytoplasm, or undergo splicing to create monocistronic mRNAs that are translated...

and omit those exons that become part of a non-coding RNA or the untranslated region of an mRNA. Such incorrect definitions still occur in overall reputable...

mRNAs for potential complementarity. Instead of destructive cleavage (by Ago2), miRNAs rather target the 3′ untranslated region (UTR) regions of mRNAs...

segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins produce messenger RNA (mRNA). Other segments of DNA...

interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA at first non-coding RNA molecules...

5′-untranslated region (5′-UTR) is a region of a gene which is transcribed into mRNA, and is located at the 5′-end of the mRNA. This region of an mRNA may...

better known as miRNAs. stRNAs exert negative post-transcriptional regulation by binding to complementary sequences in the 3' untranslated regions of their...

as microRNAs. RNA silencing may also be defined as sequence-specific regulation of gene expression triggered by double-stranded RNA (dsRNA). RNA silencing...

competing endogenous RNAs (abbreviated ceRNAs) regulate other RNA transcripts by competing for shared microRNAs (miRNAs). Models for ceRNA regulation describe...

the DNA less available for RNA polymerase. The mature messenger RNA produced from protein-coding genes contains untranslated regions at both ends which...
