What is a codon and why are they important?

To whom describe each of the following bonds and explain why they are important...a: high energy phosphate bond b: peptide c: bond between mrna codon and trna anticodon

  • Answer:

    Each ATP or GTP cleavage generates ~40 kJ/molEach peptide bond costs ~160 kJ/mol in the cell,yet an uncatalyzed chemical reaction to form a peptide bond costs only ~20 kJ/mol. The ribosome moves along the messenger RNA chain to the next codon. At the same time a peptide bond is made between the two amino acids, and the first one breaks away from its transfer RNA.
