DISASSEMBLY OF DNA WITHIN A DIGESTIVE ENZYME
Where do DNA building blocks (nucleotides) come from? From your food, of course. Food for all animals is--other organisms. Digestion is a matter of breaking down the food organism's macromolecules into their building blocks. In this case a long strand of DNA is enzymatically cleaved into four kinds of nucleotides which can be reassembled to make the new DNA molecules required for cell division. |
