Imagine you are following a particular tRNA, called tRNAQ, through the process of translation in a eukaryote. Consider the steps of tRNAQ translation. 1. The polypeptide is transferred to tRNAQ. 2. tRNAQ binds the A site of the ribosome. 3. tRNAQ binds the P site of the ribosome. 4. The ribosome shifts, with tRNAQ still bound. 5. tRNAQ binds the E site of the ribosome. In what order does tRNAQ go through the steps listed

Explanation:

A transfer RNA is a small RNA sequence (approximately 75-90 nucleotides in size) that serves as an adaptor molecule in order to link a specific triplet of nucleotides or 'codon' in the messenger RNA (mRNA) with a particular amino acid in the ribosomes during protein synthesis (i.e., during translation). The tRNAs have 1-a trinucleotide region known as the anticodon, which is a sequence complementary to a codon in mRNA, and 2-a region for attaching a particular amino acid. Moreover, a ribosome has three slots for binding tRNAs: A site, P site, and E site. The ribosomal A-site is the first location the t-RNA binds during translation; the P-site is the second binding site for tRNAs; and, finally, the E-site is the third site where deacylated tRNAs bind before their dissociation from the ribosome.
