I am not limiting God in the slightest. God is the God of science; thus, all scientific process has come from Him. It seems to me that you are suggesting that God is performing every scientific process at all times. While God could definitely do this, He does not have to because He created it all once to work like clockwork. Like a computer program, God has programmed His creation to carry out everyday functions. Does God conduct the weather? Sometimes (he has been known to influence human history with weather), but regular climate he does not have to conduct because He created the Earth to spin along its axis and rotate around the sun. He created the Gulf Stream and Coriolis Effect and caused the moon to control tides. He does not have to conduct this in real time because he set it into motion.
Does He form every baby in the womb? No, because he created the processes of cell mitosis and meiosis to work independently of his constant input. He coded the DNA in the chromosomes to take the dominant and recessive traits of the mother and father and form one cohesive human.
Does God literally feed both predator and prey out of the palms of His hands day to day? No, because He set up the ecosystems to provide for the animals.
God set up the physical laws; so, mankind bound by these laws must follow suit. Think about this, man programs software to serve different functions. Now, we expect this software to run on its own and do the tasks that the programmer has told it to do. The same can be said of DNA. Understanding DNA is vital to understanding how God created life. God initially programmed the nucleotides in the DNA to do the tasks He programmed them to do. DNA is programmed to perform every vital function any living organism could ever perform. If God would have to perform every vital function Himself then why would He create DNA?
