Genes for cytoplasmic male sterility in plants are generally located in:
- Chloroplast genome
- Mitochondrial genome
- Nuclear-genome
- Cytosol
The Correct Option is B
Solution and Explanation
Genes for cytoplasmic male sterility (CMS) in plants are generally located in the mitochondrial genome. Cytoplasmic male sterility is a phenomenon in which a plant is unable to produce functional pollen due to genetic factors located in the mitochondria. This trait is often exploited in plant breeding, particularly for the production of hybrid seeds.
So, the correct option is (B): Mitochondrial genome

Concepts Used:
Transcription
The very first stage of gene expression is the procedure of transcription. In this procedure, mRNA is the place where the genetic information is stored which later aids in encoding a protein. In this process, the DNA strand acts as a guide in the making of mRNA. Despite the fact that there is one exception which is adenine base pairs with uracil instead of thymine.
Transcription Unit:
The transcription unit is a set of freshly combined RNA molecules that have been transcribed from DNA. The cause is to encode at least one gene. A protein that has been encoded or encrypted with a DNA transcription unit may have a coding sequence. Transcription has a lower copying fidelity rate when differentiated from DNA replication.
The Stages of Transcription:
The procedure of transcription is enzymatically catalyzed into three steps:
- Initiation
- Elongation
- Termination
