← ScienceWhich mechanism causes selective peptide assembly on a ribosome?
A)Hydrogen bonding between tRNA anticodons✓
B)Electrostatic interactions with mRNA surface
C)Covalent modification with chaperone proteins
D)Hydrophobic packing of rRNA components
💡 Explanation
Specific hydrogen bonding between mRNA codons and tRNA anticodons ensures correct amino acid incorporation into the peptide sequence, because this drives the ribosome's function. Therefore, only correct peptides assemble, rather than incorrect binding based on size.
