protein to be manufactured and makes a copy of them. Sometimes,
however, the data regarding the protein to be produced may be dis-
persed in different regions. Under such circumstances, the RNA poly-
merase copies the entire region—from where the data begin to where
they come to an end. In doing so, the enzyme also copies sequences that
serve no immediate purpose.
The presence of unnecessary data will lead to the production of a
different, useless protein. In order to prevent this, a new enzyme
known as spliceosome enters the equation and removes the non-coding
intervening sequences from among hundreds of thousands of pieces of
data, then joins together the chains necessary for the manufacture of the
protein.
At this point, the tRNA codon (transfer RNA: a small RNA chain
that transports amino acids to the ribosome for protein synthesis) must
be attached to the correct amino acid. There is at least one kind of tRNA
79
for each of the 20 amino acids. If this vital stage in DNA replication
does not function properly, then the DNA sequence will be damaged
and be functionless. A special enzyme, aminoacyl tRNA synthetase, is
responsible for attaching the proper amino acid to the tRNA. During
this process it has to be ensured that every tRNA carries the correct
amino acid, and that none of the other 19 amino acids are affected.
Since the enzyme in question works without error, these risks in the
copying of DNA are totally eliminated. 80
The dilemma in DNA replication also emerges in RNA replication.
The proteins that permit RNA copying are, again, enzymes produced
by RNA. It is therefore impossible to speak of enzymes in the absence
of RNA, and vice-versa. Accordingly, evolutionists face insoluble prob-
lems regarding how RNA polymers can replicate in the absence of pro-
81
teins. RNA's particular enzymes must be working at full capacity, and
with all their functions, from the moment that RNA comes into being.
Yet at the same time, those enzymes have to be manufactured by RNA.
