Which of the Following are Characteristics of Translation Initiation? Please

Question

Which of the following are characteristics of translation initiation? Please select all that apply.
A) The initiator codon arrives at the A site
B) The first translated codon is for methionine
C) tRNA used for initiation is not used for elongation
D) Translation starts at the 5' UTR of the mRNA

Accepted Answer

During translation initiation, the initiator codon first arrives at the P site. The first codon, AUG, codes for methionine. The tRNA used for initiation is specific to initiation and does not recognize internal codons. The 5' untranslated region (UTR) is by definition not translated.
