During translation, the resulting mRNA is decoded to produce a protein consisting of amino acids in a specific sequence. In both prokaryotes and eukaryotes, it takes place on the ribosomes. In eukaryotes, though, it occurs on the ribosomes that are attached to the surface of the endoplasmic ...
Gene expression in prokaryotes as well as in eukaryotes is regulated quantitatively and qualitatively by specific upstream DNA sequences.1These DNA sequences are commonly known as gene promoters. Initiation of transcription is in turn mediated by proteins that recognize specific DNA sequences in the p...
The molecular architecture involving mRNA splicing and PTMs are quite similar in higher eukaryotes and S. pombe. The study of the mammalian introns getting spliced appropriately, when expressed in S. pombe system, justifies the same. Also, at the gene level, the mammalian promoters and poly (A...
Informational implications of gene function in eukaryotes include: the nuclear DNA reversion, feedback from nucleus to cytoplasm, gene activity in coupling and repulsion phases, branching enzymes and the ectopic expression of gene and aberrant transcripts. In addition to the academic goals of perceiving...
For prokaryotes, translational efficiency was identified as the main source of variability of expression levels consistent with a stochastic model in which proteins are produced in sharp and random bursts (Ozbudak et al., 2002). However, later experimental observations in individual living cells ...
Controlling gene expression in response to specific molecules is an essential technique for regulating cellular functions. However, current platforms with transcription and translation regulators have a limited number of detectable molecules to induce ge

Regulation of Genes Genes can be turned on or off Off = not active, not making proteins – Tightly wound – DNA covered in methyl groups On = active, making proteins – Not tightly wound – Acetyl groups attached to histones Other ways to control gene expression… Introns vs exons Activity...
Alternative names have since been used for this octocoral gene to infer relationship specifically to the MSH1 family ("msh1" [16, 17]) or to encompass broad taxonomic ranges ("mtMutS" [18]), including MMR genes from both prokaryotes (MutS) and eukaryotes (MSH). We hereafter preferentially...
