Translation: Von RNA zum Protein

Translation
Translation
Lesson: Translation Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following ...
tRNA-Aktivierung
tRNA-Aktivierung
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 ...
Ribosomen
Ribosomen
Ribosomes translate genetic information encoded by messenger RNA (mRNA) into proteins. Both prokaryotic and eukaryotic cells have ribosomes. Cells that ...
Verbesserung der Translationsgenauigkeit
Verbesserung der Translationsgenauigkeit
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single ...
Initiierung der Translation
Initiierung der Translation
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are ...
Termination der Translation
Termination der Translation
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the ...
Nonsense-mediated mRNA Decay
Nonsense-mediated mRNA Decay
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual ...
Molekulare Chaperone und Proteinfaltung
Molekulare Chaperone und Proteinfaltung
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form ...
Das Proteasom
Das Proteasom
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the ...
Regulierter Proteinabbau
Regulierter Proteinabbau
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a ...
Proteine: Von den Genen bis zur Degradierung
Proteine: Von den Genen bis zur Degradierung
Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This ...
