b. It fixes stalled mRNA synthesis that lacks an anticodon by synthesizing the appropriate tRNA required for the ribosome to continue translating.
c. It forms the structural backbone of ribosomes but is not directly involved in translation.
d. It helps initiate translation by base pairing with the ribosome binding site (RBS) on the mRNA.
