Getting the Order Ready

As a result of the processes enumerated in the previous section,
the instructions needed for the order for the particular protein are
transferred by enzymes from the DNA to the messenger RNA
(mRNA). Now it's the ribosomes' turn to manufacture the particular
protein, according to orders given them by the DNA. The ribosome
manufactures a substance to the exact specifications desired. The
structural plan of the ordered protein is also found in the mRNA. The
mRNA, together with the instructions it has copied from the DNA,
moves out of the nucleus and towards one of the ribosomes found in
the cytoplasm, to which it binds. An amino acid, corresponding to
each codon in the mRNA, is brought to the ribosome by transfer RNA
(tRNA), and attached to the relevant site. To one end of the tRNA is
attached the anticodon of one of the codons in the mRNA, and on the
other end is the amino acid represented by the codon. As the tRNA
binds to the codon in the mRNA that corresponds to its own anti-
codon, the amino acid it bears is automatically placed in the correct
sequence.
There are 20 different tRNA molecules for the 20 different amino
acids used. Each amino acid can bind only to its own tRNA. This is
because in order for them to bind to each other, their three-dimen-
sional shapes have to fit together exactly (see Figure 3.7). The fact that
the tRNA and the amino acids, composed of thousands of atoms, have
been made to fit together is a proof of the harmony and perfection in
God's creation. God is the Creator, the Maker, the Giver of Form (al-
Bari) (Qur'an, 59:24).
Thousands of amino acids join together to form the desired
polypeptide chain (or protein molecule), according to the thousands of
instructions found on the mRNA arriving at the ribosomes on which
the protein is synthesized. Not even one extra amino acid is included
in the mRNA plan to be attached to this molecule. No amino acid
attaches to a different site than what the plan requires, and no amino
