(prolekarniky.cz)
First, a pre-mRNA is spliced, causing the 3′-hydroxyl of the upstream exon to covalently bond to the 5′-phosphate of the downstream exon. (biomedcentral.com)

Generally, TAG biosynthesis takes place in the endoplasmic reticulum, and TAG assembly can be divided into acyl-CoA-dependent and acyl-CoA independent pathways [10]. (researchsquare.com)

The goal of our research group is to elucidate the molecular mechanisms underlying the initiation phase of protein synthesis in eukaryotic organisms. (nih.gov)
What is involved in protein folding mechanisms, and what is the role improper protein folding can play in disease? (mit.edu)
Previous studies have demonstrated that lncRNAs act as one of the molecular mechanisms for the post-transcriptional regulation and modulation of protein function. (biomedcentral.com)

Dna is housed within the nucleus, and protein synthesis takes place in the cytoplasm, thus there must be some sort of intermediate messenger. (caisouthern.com)
Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. (bvsalud.org)

The purpose of this study was to determine the mRNA levels in the yeast mutant rpc128-1007 and its overdose suppressors, RBS1 and PRT1. (mdpi.com)

The availability of multiple PAS in the same 3' regulatory region enables the inclusion or exclusion of 3' untranslated region (3'UTR) sequences, resulting in transcripts that may differ in particularities involving post-transcriptional processes such as stability, transport and translation ( Mayr, 2016 ), and even protein localization ( Berkovits and Mayr, 2015 ). (frontiersin.org)
Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. (bvsalud.org)

FMRP links optimal codons to mRNA stability in neurons. (umassmed.edu)
The 3' regulatory regions have a great diversity of cis -regulatory elements directly involved in polyadenylation, stability, transport and mRNA translation, essential to achieve the desired levels of gene expression. (frontiersin.org)
Polyadenylation is essential for the stability of the transcript, preventing the mRNA from being the target of posttranscriptional gene silencing (PTGS) via RNA-dependent RNA polymerase 6 (RDR6) in plants ( Luo and Chen, 2007 ). (frontiersin.org)
Small regulatory RNAs can modify the activity of proteins and the stability and translation of mRNAs. (illinois.edu)

The altered splicing pattern and 3'-end heterogeneity of the alternative poly(A)+ mRNAs would result in preferential translation of small T-Ag (to a greater degree) and middle T-Ag over large T-Ag at later times in the polyomavirus lytic cycle. (ox.ac.uk)

It is the "factory" where amino acids are assembled into proteins. (wikidoc.org)

Base pairing then triggers downstream events that commit the PIC to continuing initiation from that point on the mRNA. (nih.gov)

In proteins, the complementarity between sense and antisense peptides depends on a specific hydropathic pattern, where codons for hydrophilic and hydrophobic amino acids in a sense peptide are complemented by the codons for hydrophobic and hydrophilic amino acids in its antisense counterpart.
