34. DNA and Proteins
DNA cannot function without hundreds of preexisting proteins,a but proteins are produced only at the direction of DNA.b Because each needs the other, a satisfactory explanation for the origin of one must also explain the origin of the other.c Therefore, the components of these manufacturing systems must have come into existence simultaneously. This implies creation.
Some of these necessary protein systems decode the DNA, transcribe it into messenger RNA, and assemble it using extremely complex ribosomes, which are composed of proteins.
One of the most studied proteins in mammals, including humans, is called p53. It binds to thousands of DNA sites and influences cell growth, death, and structure. It is involved in fertility and early embryonic development. It also stifles cancers by repairing DNA, suppressing tumors, and killing genetically damaged cells.d How could DNA have survived unless p53 and its many functions already existed?
In each human, tens of thousands of genes are damaged daily!e Also, when a cell divides, its DNA at times is copied with errors. Every organism has machinery that identifies and repairs damaged and mistranslated DNA.f Without such repair systems, the organism would quickly deteriorate and die. If evolution happened, each organism would have become extinct before these DNA repair mechanisms could evolve.
Life’s complexity is mind boggling—not something that random process could ever produce.
