"Living creatures not only contain enormously complex machines, they also contain the ‘instruction manual’ to build these machines—which can be seen as a sort of ‘recipe book’ programmed on DNA, the famous ‘double helix’ molecule (deoxyribonucleic acid).... two of its remarkable features:
only with G. Due to the chemical structure of the bases, each pair is like a rung or step on a spiral staircase, the famous ‘double helix’ shape. Each DNA molecule has two strands, effectively the sides of the spiral staircase. The letter pairs form the steps, with A always opposite T and C always opposite G. The two strands can be separated and copied independently to form TWO spiral staircases, such that the new strands are exact copies of the original information.
The copying is far more precise than laboratory chemistry could manage, because there is editing (proof-reading and error-checking) machinery, again encoded in the DNA. This machinery keeps the error rate down to less than one error per 100 million letters. But, since the editing machinery itself requires proper proofreading and editing during its manufacturing, how would the information for the machinery be transmitted accurately before the machinery was in place and working properly? Lest it be argued that the accuracy could be achieved stepwise through selection, note that a high degree of accuracy is needed to prevent ‘error catastrophe’ in the first place—from the accumulation of ‘noise’ in the form of junk proteins specified by the damaged DNA.
DNA is a very complicated molecule, and actually a very unstable one. DNA researchers often need to store it in liquid nitrogen, at –196°C (77 K; −320°F), and even that frigid temperature doesn’t entirely stop breakdown.
Fortunately, in our cells, we have many elaborate repair machines to undo this chemical damage. But most skeptics believe that life evolved in a primordial soup, which would have lacked such machines (not to mention the lack of any evidence that it existed at all). So even if DNA managed to form spontaneously somehow, it would not have survived long.
For the past two decades, Dr Mary Schweitzer, although a committed (theistic) evolutionist herself, has been rocking the evolutionary/uniformitarian world with discoveries of soft tissue in dinosaur
bones. These discoveries have included ligaments, blood and bone cells; flexible blood vessels; proteins like collagen, osteocalcin, actin, and histones, and most importantly, DNA. Her team detected DNA in three independent ways, including DAPI, which lodges in the minor groove of a DNA double helix. This shows that the DNA was quite intact, since short strands of DNA less than about 10 ‘letters’ don’t form stable duplexes.
However, a recent paper on DNA stability estimates that, even when preserved in bone, it would be completely disintegrated down to single ‘letters’ in 22,000 years at 25°C (77°F), 131,000 years at 15°C (59°F), 882,000 years at 5°C (41°F); and 6.83 million years at –5°C (23°F).
Note also, dinosaurs mostly lived in a warm climate, where DNA would break even more quickly,..

- Surprising chemical instability.
