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.
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
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.
Mitochondria are pre existed aerobic bacteria kind.So they have their own DNA.It is circular DNA.
because when they become weak they urgently need to diviide them as they are impprtant part pf cell
They have evolved from bacteria. So they have some bacterial features.
Mitochondria said to be pre existing bacteria.They have circular DNA like bacteria.
They are thought to exist from bacteria. So they have their own DNA etc
it doesn't.
Two of the cellular organelles that have their own DNA are chloroplast and a nucleus. The mitochondrion also have there own DNA.
They have own circular DNA and ribosomes.So they can reproduce.
Mitochondria and chloroplasts have their own DNA.
Both chloroplasts and mitochondria have double membranes and their own DNA.
Both have their own DNA and are surrounded by a double menbrane
Two of the cellular organelles that have their own DNA are chloroplast and a nucleus. The mitochondrion also have there own DNA.
They desend from bacteria.So they have their own DNA
It is thought that mitochondria were once bacteria as they have their own DNA and it is similar to bacterial DNA.

They have their own DNA.They have circular DNA.
Yes they have their own DNA.They have circular DNA.
