Today we're discussing the central dogma of biology, and that's going to help us answer a couple questions down the line.
00:10
So before i start with the central dogma itself, i want to talk about dna replication.
00:19
Dna replication from the word itself replication means dna just makes more of itself.
00:26
And this happens during the interface.
00:35
Of the cell when the cell prepares for cell division so we're replicating dnas we have more of it and we can split it into during cell division this process is facilitated by an enzyme called dna polymerase dna polymerase so that's that's dna replication and say we have a cell that wants to make protein.
01:17
That's when we enter the central dogma of biology.
01:21
Because we want to make protein from dna.
01:29
And the way we do that is we go from dna to rna and eventually protein.
01:37
So we start with a process called transcription.
01:42
So this is when we make rna from our dna template.
01:51
So we make rna from dna and this process is facilitated by an enzyme called rna polymerase.
02:05
So remember when we're making dna, we use dna polymerase.
02:13
When we're making rna, we use rna polymerase.
02:18
And before we translate that rna into protein, one of the things that we, um, lot of times leave out and the central dogma is what we call rna processing rna processing so the rna that we get from dna actually contains a lot of junk right so there's there's areas say this is let's say this is our rna there's certain areas in there that don't really encode for protein so we have to get rid of those and the way we do that is through rna processing.
03:11
So this is the process of removing introns...
