86 THE MIRACLE OF PROTEIN
as a flawless chain of amino acids. Ribosome uses more than one
hundred helper molecules, which operate in perfect coordination
to ensure that the translation system works flawlessly. These mol-
ecules are special RNAs sent to the production center and most
22
of them are specialized proteins. The most important of these is
ribosomal RNA, which allows information brought to the ribo-
some by the messenger RNA to be understood and read in a dif-
ferent language by the transfer RNA. During the error-free trans-
lation process, each one of these prepared mechanisms must
work in a flawless manner for the correct protein to emerge.
mRNA and tRNA match each other like a lock and
key, which allows the DNA language to be translated
into protein language. Every third letter in the mRNA
is like a key, and the end of the tRNA that corre-
sponds to it, is like a lock that opens this key.
