Some Events that Occur in a Cell during the Synthesis of Proteins
    1. mRNA nucleotides are fused into a long chain.
    2. Amino acids join in a chain.
    3. Double helix of DNA uncoils.
    4. Polypeptide is released.
    5. tRNA anticodons match with mRNA codons.
    6. mRNA attaches to a ribosome.
The sequence in which these events occur is
