Subjective Type

Mitochondria and plastids have their own DNA (genetic material). What is known about their fate during nuclear division like mitosis?

Solution

The DNA in mitochondria and plastids Is extra-genomic DNA. It has no correlation with the nuclear division during mitosis. Hence, karyokinesis during cell division has no effect on extra-genomic DNAs.
