From the dna perspective is aging just telomeres and methylation?

Oh so basically looking at dna we can see all the possible proteins that we have the ability to create? I wasn’t sure if they did some like Lego stuff and some proteins naturally conjoined to other to form even more proteins but then I guess with the technology you still be able to figure out possible combinations based on their shapes. I’m surprised this isn’t talked about more. Does this mean we would also be able to create proteins that could get rid of the stuff our body doesn’t naturally break down? I read an article on the immortal jellyfish. If they had their genome sequenced couldn’t they see all the proteins and make a conjecture based on shape to see which ones are responsible for the “reverse aging”

Oh ok that’s pretty cool. So we basically just gained a bunch of information we didn’t have before and save on resources time and labor. I didn’t realize it was so hard to see proteins. Since they are so hard to see how do we know we have all the human proteins. Are they just brute force scanning things in the human body?

How were we able to know how they folded before? If it was something like a microscope couldn’t we have already just observed most proteins already. I’m assuming it’s big thing is making recipes for proteins in shapes that we desire?

So what is important about it? From what I read it predicts how proteins fold. I’m not versed enough to know the impact that has.
