Transkripsiyon: RNA'dan Proteine

Translasyon
Translasyon
Lesson: Translation Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following ...
tRNA Aktivasyonu
tRNA Aktivasyonu
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 ...
Ribozomlar
Ribozomlar
Ribosomes translate genetic information encoded by messenger RNA (mRNA) into proteins. Both prokaryotic and eukaryotic cells have ribosomes. Cells that ...
Translasyonel Doğruluğun Geliştirilmesi
Translasyonel Doğruluğun Geliştirilmesi
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 ...
Translasyonun Başlatılması
Translasyonun Başlatılması
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are ...
Translasyonun Sonlandırılması
Translasyonun Sonlandırılması
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the ...
Anlamsız aracılı mRNA Bozulması
Anlamsız aracılı mRNA Bozulması
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual ...
Moleküler Şaperonlar ve Protein Katlanması
Moleküler Şaperonlar ve Protein Katlanması
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 ...
Proteazom
Proteazom
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the ...
Düzenli Protein Degradasyonu
Düzenli Protein Degradasyonu
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 ...
Proteinler: Genlerden Degradasyona
Proteinler: Genlerden Degradasyona
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 ...
