Marine Biologist, Dr Rob Carter (PhD) explains,
In the naive concept of DNA, we had a line that had information in it. But it’s not simple like that, because this piece of DNA makes a little protein that comes over here and sticks on this piece of DNA over here, which turns on or turns off a gene.
The genome also folds into a three-dimensional shape… the genes that are buried inside this ball of DNA … they’re not active. They’re turned off. The genes that are exposed are the ones that are used. So whoever programmed that string knew, when it folded up, which genes will be available at what time… when this instruction set folds onto itself, it creates a whole new set of instructions
