Cells contain several types of RNA. Messenger RNA (mRNA) is a copy of protein coding genes of DNA that is used for protein production. Ribosomal RNA (rRNA) is used for the structure and function of ribosomes. Transfer RNA (tRNA) is used to bring amino acids to the ribosome during protei...
aA third tRNA, complementary to the next codon, enters the A-site, a peptide bond forms between amino acids 2 and 3, and then the second tRNA moves into the E-site of the ribosome, and exist. 第三tRNA,补全到下密码子,进入站点,缩氨酸键形成在氨基酸2和3之间,第二tRNA然后搬入核糖体的E站...
Phosphorylated eIF2α (P-eIF2α) inhibits recycling of its GTP-bound form (active) by eIF2B, which is required for delivery of the methionyl-tRNA to the ribosome during translation initiation [94]. In addition, P-eIF2α also elicits preferential translation of mRNAs containing an upstream ...
