So what is a mutation? by definition in molecular biology, a mutation is a change in the dna sequence.
00:08
This could be something like you delete this, or you delete this g.
00:12
So now the sequence is just a, t, a, g, or maybe that g turns into a c.
00:19
So now the sequence is a, t, c, a, g.
00:22
So a mutation is just a change in the dna sequence.
00:26
And these can come from many different reasons.
00:29
They don't have to just be caused by radiation.
00:30
Maybe dna preliminaries while replicating it will misread this instead of reading an a.
00:36
It'll read a t and then i'll add an a.
00:39
And so, mutations can come from many different sources...
