Hello everyone in this question we will be discussing about mitochondrial.
00:05
So mitochondrial e basically refers to my mitochondrial dna.
00:13
The unique genetic code that is passed down from the female to the female as the cytoplasmic content is passed on from the mother, not from the father.
00:30
And the mitochondrial dna is responsible for the energy metabolism and it has its own dna that is derived from the endosimbiosis theory because the dna here is similar to that of the prokaryotic bacteria.
00:49
The endosimbiosis theory suggests that the cell engulfed an aerobic bacteria and this aerobic bacteria and this aerobiasis, with bacteria performed cellular respiration and due to which the energy was generated.
01:07
And after evolution, it stayed inside the cell only and developed into mitochondria.
01:14
That is why the mitochondria has its own dna.
01:20
As this bacteria and the cell were in symbiotic relationship, so the destruction of the cell was not taken place.
01:27
So the mitochondrial dna is passed down the metrilineal line from generation to generation.
01:34
Now in the next question we have been asked about the y -chromosomal atom.
01:41
So y -chromosomal most recent common ancestor, y -r -ca, most recent common ancestor, is informally known as y -chromosomal atom...
