Only the initiator tRNA can initiate translation
B
Only one ribosome can translate a gene at a time
C
Each tRNA must be passed through three sites on the ribosome
D

Verified step by step guidance1
Understand the process of translation, which is the synthesis of proteins from mRNA templates. It involves the ribosome, tRNA, and various other factors.
Recognize that translation begins with the initiator tRNA, which carries the first amino acid and binds to the start codon on the mRNA.
Learn that multiple ribosomes, known as polyribosomes or polysomes, can simultaneously translate a single mRNA molecule, allowing for efficient protein synthesis.
Identify the three sites on the ribosome that tRNA molecules pass through during translation: the A (aminoacyl), P (peptidyl), and E (exit) sites.
Understand that the large subunit of the ribosome is responsible for catalyzing the formation of peptide bonds between amino acids, thus elongating the polypeptide chain.
