Transcriptionis the first step in protein synthesis wherein DNA acts as a template for the generation of mRNA or messenger RNA. During this process, the information encoded in DNA for each protein is tra...
The composition of codons in thecoding regioncan be affected by mutations, selection[1], andgeneticdrift[2–4]. Specifically, the selection can be related to frameshifting and various central intracellular phenomena such as transcription, translation,mRNA stability,RNAandDNA methylation, co-translational...
Specifically, the selection can be related to frameshifting and various central intracellular phenomena such as transcription, translation, mRNA stability, RNA and DNA methylation, co-translational folding, splicing, transport, and more (see review in [5–7]). Thus, techniques for analyzing codon ...
chromosomal stability, damage DNA, cause inflammation, disease and/or cell death. For example, increased levels of endogenous retroviruses (ERV), a TE subclass,trigger fibro inflammationand play a role in kidney disease development. However, in mammals, the transcription of TEs is important for ma...
A process to translate mRNA into polypeptides outside of a cell into a cell-free system made of cytoplasm from burst E. coli cells with all materials required for translation. For example, Nirenberg made an mRNA molecule containing only Uracil nucleotide (poly-U). Then he added this mRNA to...
Fig. 5: Distances between codon-specific Ramachandran plots are related to parameters of the translation process. Left: The mean absolute difference in the relative translation speed as a function of the mean distance between backbone dihedral angle distributions for pairs of codons translated unambiguou...
example, transcript levels are also altered in cancer at the level of mRNA stability [4,5]. In addition, rapid division and growth of the cancer cells requires increased protein synthesis. To facilitate this, mRNA translation is often dysregulated in tumour cells and the surrounding stroma [6]...
For instance, in yeast (Saccharomyces cerevisiae), rare genomic codons exhibit enhanced use in stress genes, and tRNAs matching these codons have been found to be upregulated in response to stressful conditions, allowing improvement of their translation levels without any change in transcription rates...
Background: The expression of both the env and gag gene products of human immunodeficiency virus type 1 (HIV-1) is known to be limited by cis elements in the viral RNA that impede egress from the nucleus and reduce the efficiency of translation. Identifying these elements has proven difficult...
Despite their essential function in terminating translation, readthrough of stop codons occurs more frequently than previously supposed. However, little is known about the regulation of stop codon readthrough by anatomical site and over the life cycle of
