Options
- Amitochondrial genome
- Bcytosol
- Cchloroplast genome
- Dnuclear genome
Correct answer
A. mitochondrial genome
Step-by-step solution
Mitochondria are the eukaryotic cell organelles (do not present in prokaryotic cells). These originate from pre-existing mitochondria only. Mitochondria are also known as semi autonomous organelles because they contain a circular, double stranded DNA molecule, RNA and 70 S type of ribosomes. The genes, located outside of nucleus (i.e., within the cytoplasm) also governes some traits, are referred to as plasmogenes or cytoplasmic genes. Cytoplasmic male sterility (i.e., dominance of female cytoplasmic genes over mal
