  • A water molecule is removed during a biological process that links the carboxyl group of one amino acid to the amino group of a nearby amino acid to generate peptide bonds.
  • The main structure of a protein is thought to be its linear amino acid sequence.
  • A codon is a cluster of three mRNA nucleotides that codes for a particular amino acid.
  • Each mRNA produces a protein that has a specific amino acid sequence corresponding to it. The start and stop of translation are indicated by two codons known as start and stop codons.
