Let's look at the first Wikipedia sentence on tyrosine kinase as a starting point:
"A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to the tyrosine residues of specific proteins inside a cell."
What's ATP? We both know what ATP is. Is ATP deeply part of metabolism? We both know it almost is a definition of metabolism. I want to shout at you. But I don't know who you are or how to connect with you.
Please, for the love of anything that you find Holy, instead of arguing with me on the internet do this: Read the books I recommended, and start looking for the links to metabolism like I just did for you instead of trying to "see DNA everywhere". You will go so much further and help all of us than just arguing with me.
