In order to answer this question, let's talk about dna replication.
00:03
It says, a deletion occurs in a gene that then calls for dna polymerase 1 in e.
00:09
Coli.
00:09
In non -functional dna polymerase, 1 is produced.
00:13
What will be the most likely consequence of this mutation? so, in general, remember that when you have your dna scan here, okay, in order to synthesize the new dorer strand, you acquire an enzyme called dna polymerase 3.
00:31
And this dna polymerase 3 is the one that is going to start synthesizing the new doral strand of dna.
00:37
But this enzyme cannot start synthesizing out of nothing.
00:41
It requires a short segment of rna that is known as primary.
00:46
And this primary is placed by the enzyme rna primates.
00:51
So once you have placed your primary here, your dna polymerase is going to come and it's going to start synthesizing your daughter dna strand.
01:01
After this, remember that your dna must be only dna.
01:06
It shouldn't contain rna.
01:08
So this is where dna polymerase 1 comes...
