The Hidden Genome: How Mitochondrial DNA Shapes Aging and Disease
D
9:44Deborah WestphalHOST
Can you explain how you can see the change, you know, kind of that phase change? And then how much diversity is there between each one of these cells when you look at them aggregate as well as just one cell?
S
10:01Stefan IsaacGUEST
So as far as, like, how we're able to see, so at the single base level, we're able to see a couple of different things.
S
10:08Stefan IsaacGUEST
One of them is mutations, so which is going to be relative to a reference genome.
S
10:14Stefan IsaacGUEST
So we can see this is what people say the sequence of mitochondrial DNA is, and we can see in this cell there are this many mutations, and we can, you know, either understand what their role is because they're maybe associated with diseases, or we can predict their functional impact.
S
10:29Stefan IsaacGUEST
And so there, you know, one thing you could do is follow these systems over time and look at the changes in the population that have those mutations or those larger deletions.
S
10:41Stefan IsaacGUEST
And the other thing that we're able to do is these technologies can read out on different, essentially incorporating chemistries to understand other feed out-- other readouts other than, um, just the sequence.
D
13:28Deborah WestphalHOST
Like, how close are we to, to really kind of understanding, like, what is really going on?
