Which one of the following has its own DNA?
Mitochondria
Dictyosome
Lysosome
Lysosome
A.
Mitochondria
In mitchondria, the inner membrane space is filled with a matrix which contains dense granules along with ribosomes and mitchondrial DNA.The mitochondrial DNA is circular in nature. There number varies from 2-6.Besides DNA, a mitochondrion has RNA and its ribosomes also. Thus, a complete protein synthesizing machinery is present in mitcochondria, which suggeststhe semi -autonomuous nature of mitochondria Dictyosome, lysosome and peroxisome do not have their own DNA.
