Identify one aspect of translation that is present in Bacteria but absent in Eukarya: Group of answer choices :
rRNA in the large subunit of the ribosome plays a catalytic role
The elongation stage is sensitive to the presence of diphtheria toxin
The genetic code consists of 64 unique 3-nucleotide codons
A peptide bond forms between the amino acid of one amino-acylated tRNA and a peptide on the other tRNA
An tRNA carrying methionine is recruited to the ribosome to form the initiation complex
The small subunit rRNA molecule anneals to the Shine-Dalgarno sequence on the mRNA
