Messenger RNA - Wikipedia
The structure of a mature eukaryotic mRNA. A fully processed mRNA includes a 5' cap, 5' UTR, coding region, 3' UTR, and poly(A) tail.
Messenger RNA (mRNA)- Definition, Structure, Processing, Types, …
2023年8月3日 · All eukaryotic mRNA is monocistronic, and they all go through post-translational modification to initiate protein synthesis. It is transcribed from a single gene (cistron) and has one initiation and termination codon.
15.8: RNA Processing in Eukaryotes - mRNA Processing
2024年11月23日 · The eukaryotic pre-mRNA undergoes extensive processing before it is ready to be translated. The additional steps involved in eukaryotic mRNA maturation create a molecule with a much longer half-life than a prokaryotic mRNA.
mRNA Fact Sheet: Definition, Structure, Function, and Association …
In eukaryotes (organisms containing a clearly defined nucleus), the structure of mRNA molecules is more elaborate. The 5′-triphosphate residue is further esterified, forming a cap structure. The 3′ ends typically contain a poly (A) tail that consists of multiple adenosine monophosphates and is added enzymatically after transcription.
mRNA Structure and Function - ScienceDirect
1977年1月1日 · It discusses the general structure of eukaryotic mRNA for the majority of the molecules. It reviews that a number of gaps in the knowledge about the function of mRNA still exist—for example, the mechanism and regulation of mRNA turnover.
mRNA structural features: (a) a basic structure of a eukaryotic mRNA ...
... eukaryotic cells, mature mRNA is generally comprised of five distinct portions (Fig. 1a): (i) a cap structure, (ii) a 5′ untranslated region (5′ UTR), (iii) an open reading frame (ORF),...
mRNA Processing in Eukaryotes: A Comprehensive Guide - Go Life …
2024年8月3日 · A mature eukaryotic mRNA typically has the following structure: 5′ cap: A modified guanine nucleotide at the 5′ end; 5′ untranslated region (UTR): Regulatory sequences before the start codon; Coding sequence: The portion that codes for the protein; 3′ UTR: Regulatory sequences after the stop codon
Functional 5′ UTR mRNA structures in eukaryotic translation …
In this Review, we discuss the current mechanistic understanding of structures in 5′ untranslated regions (UTRs) of eukaryotic mRNAs and the emerging methodologies used to explore them.
Dynamics of Eukaryotic mRNA Structure during Translation
Eukaryotic mRNAs are mostly monocistronic, i.e. encode one protein and contain the following structural elements (Fig. 1a): 5' end protected by cap structure; 5' untranslated region (5' UTR); protein coding sequence and 3' UTR that ends by poly (A) tail.
RNA Processing: Eukaryotic mRNAs ¥ Eukaryotic mRNAs have three main parts (Figure 13.8): Ð5! untranslated region (5! UTR), ¥varies in length. ÐThe coding sequence ¥speciÞes the amino acid sequence of the protein that will be produced during translation. ¥It varies in length according to the size of the protein that it encodes.
