WebbThrough the process of tRNA “charging,” each tRNA molecule is linked to its correct amino acid by one of a group of enzymes called aminoacyl tRNA synthetases. Figure 11.7: … WebbmRNA and tRNA molecules differ in the type of sugar found in their backbone. Whereas mRNA contains a ribose sugar, the backbone of tRNA molecules contains the sugar D-Galactinol, which is more stable and resistant to cleavage by enzymes. As a result, tRNA molecules have a greater degree of stability than mRNA. The difference in the structure …
WebbPhosphorylation of the alpha subunit of the eukaryotic initiation factor 2 (eIF-2alpha) is one of the best-characterized mechanisms for downregulating protein synthesis in mammalian cells in response to various stress conditions. In Drosophila, such a regulatory mechanism has not been elucidated. WebbThis initiation complex then recruits the second tRNA and thus translation begins.The small subunit It proceeds to scan the mRNA in the 5'-->3' direction until it encounters …
