Difference between DNA vs mt DNA ( mitochondrial dna)

1) DNA - found in nucleus

mt dna - found in mitochondria only

2) DNA - linear

mt DNA - circular

3) DNA - 46 chromosomes

mt DNA - 1 chromosomes

4) DNA - inherit from both parents

mt DNA - inherit from mother only

5) DNA - for genetic make-up

mt DNA - for mitochondria metabolic activity

6) DNA - contain intron

mt DNA - no intron

Hi Vikki,

Thank you for your kind help!

I am actually asking about the difference between mitochondrial ribosome RNA gene and nuclear ribosome RNA gene.

I'd appreciate it if you could comment on that.

Thanks again!

Thanks, Mitesh! Appreciated it!

Mitochondria have their own rDNA (that looks similar to bacterial rDNA) since the modern mitochondria organelles are descended from an ancestral bacteria. While the majority of proteins in mitochondria are now coded in nuclear DNA, a handful are still made inside mitochondria. That's why the mitochondrial genome also codes for transfer RNAs.
