Sagot :
AnswerAll multi-cellular life forms have them. In some organisms the DNA that codes for the mitochondrion has been moved into the nucleus and become part of the DNA of the host cell, but in vertebrates the mitochondria keep their own DNA inside themselves.
Explanation:
Answer:
Mitochondria are found in all eukaryote organisms, unlike prokaryotes. Both nucleus and mitochondria have their own DNA. The DNA of mitochondria is called mitochondrial DNA. The mitochondrial DNA helps in the production of ATP that produces energy whereas the DNA in the nucleus is the genetic material of the cell.
Explanation:
- The presence of DNA inside the mitochondria is because of the fact that mitochondria are believed to be a primitive bacterium that was consumed by a eukaryote and became an essential organelle of the eukaryotic cell. Today, mitochondria exist only inside a eukaryotic cell serving as the powerhouse of the cell and containing mitochondrial DNA containing 37 genes. Advantaged of DNA in both nucleus and mitochondria:
- Advantages of DNA found in mitochondria and nucleus are:
- 13 genes of mtDNA perform the function of oxidative phosphorylation.
- Other genes help in the formation of tRNA and ribosomes which helps in efficient protein synthesis and production of ATP.
- The presence of a high number of mtDNA in the cell helps in producing a great amount of energy for the functioning of the cell.
