  2. Messenger RNA - Wikipedia

    en.wikipedia.org/wiki/Messenger_RNA

    Other mRNAs also move into dendrites in response to external stimuli, such as β-actin mRNA. [13] For export from the nucleus, actin mRNA associates with ZBP1 [ 14 ] and later with 40S subunit . The complex is bound by a motor protein and is transported to the target location ( neurite extension ) along the cytoskeleton .

  3. microRNA - Wikipedia

    en.wikipedia.org/wiki/MicroRNA

    The actual work of RNA silencing is performed by RISC in which the main catalytic subunit is one of the Argonaute proteins (AGO), and miRNA serves as a template for recognizing specific mRNA sequences. The function of miRNAs appears to be in gene regulation. For that purpose, a miRNA is complementary to a part of one or more messenger RNAs (mRNAs).

  4. RNA-induced silencing complex - Wikipedia

    en.wikipedia.org/wiki/RNA-induced_silencing_complex

    This shows the characteristic hallmark of RNAi: the reduced levels of mRNAs correspond to the levels of dsRNA added. To test whether their observation of decreased mRNA levels was a result of mRNA being targeted directly (as suggested by data from other systems), Drosophila S2 cells were transfected with either Drosophila cyclin E dsRNAs or ...

  5. Three prime untranslated region - Wikipedia

    en.wikipedia.org/wiki/Three_prime_untranslated...

    The IRE is a stem-loop structure within the untranslated regions of mRNAs that encode proteins involved in cellular iron metabolism. The mRNA transcript containing this element is either degraded or stabilized depending upon the binding of specific proteins and the intracellular iron concentrations. [3] Stem-loop structure of an RNA molecule

  6. RNA splicing - Wikipedia

    en.wikipedia.org/wiki/RNA_splicing

    Diagram illustrating the two-step biochemistry of splicing. Spliceosomal splicing and self-splicing involve a two-step biochemical process. Both steps involve transesterification reactions that occur between RNA nucleotides. tRNA splicing, however, is an exception and does not occur by transesterification. [25]

  7. Translation (biology) - Wikipedia

    en.wikipedia.org/wiki/Translation_(biology)

    Overview of eukaryotic messenger RNA (mRNA) translation Translation of mRNA and ribosomal protein synthesis Initiation and elongation stages of translation involving RNA nucleobases, the ribosome, transfer RNA, and amino acids The three phases of translation: (1) in initiation, the small ribosomal subunit binds to the RNA strand and the initiator tRNA–amino acid complex binds to the start ...

  9. Post-transcriptional modification - Wikipedia

    en.wikipedia.org/wiki/Post-transcriptional...

    The pre-mRNA processing at the 3' end of the RNA molecule involves cleavage of its 3' end and then the addition of about 250 adenine residues to form a poly(A) tail.The cleavage and adenylation reactions occur primarily if a polyadenylation signal sequence (5'- AAUAAA-3') is located near the 3' end of the pre-mRNA molecule, which is followed by another sequence, which is usually (5'-CA-3') and ...
