Why is your mitochondria has its own DNA?

Answer 1

It is thought that mitochondria became part of eukaryotic cells by a process known as endosymbiosis. This means that, at one time, mitochondria were free living organisms and, as such, had to be able to live on their own. This is why they have DNA, ribosomes, and enzymes. The free living cells needed DNA and ribosomes to make proteins, such as enzymes. When they were endocytosed (engulfed) by other cells, they kept these things and became organelles in charge of making energy in the new cells.

Answer 2

Mitochondria have their own DNA because they are thought to have evolved from ancient bacteria that formed a symbiotic relationship with early eukaryotic cells. Over time, some of the bacterial genes were transferred to the cell nucleus, but mitochondria have retained some of their own DNA to control essential functions like energy production.

Answer 3

mitochondria and chloroplast have thought to be evolved earlier. they used to be separate living species which had their own DNA to synthesize their own food and energy, they were later on engulfed by other larger living species (thought to be the cell) and now are the intercellular organelles in a cell

Answer 4

Mitochondria were originally separate free-living organisms, but have evolved to become organelles. Only a portion of their original DNA still remains in the mitochondria.

Answer 5

he made great contributions in the field of cell Biology.

Answer 6

Mitochondria are pre existed aerobic bacteria kind.So they have their own DNA.It is circular DNA.

Answer 7

because when they become weak they urgently need to diviide them as they are impprtant part pf cell

Answer 8

They have evolved from bacteria. So they have some bacterial features.

Answer 9

Mitochondria said to be pre existing bacteria.They have circular DNA like bacteria.

Answer 10

They are thought to exist from bacteria. So they have their own DNA etc
