Difference between Polycistronic and Monocistronic mRNA

Eukayotic mRNA molecules are monocistronic, containing the coding sequence only for one polypeptide.
In prokaryotes individual bacterial mRNA molecules are polycistronic having transcripts of several genes of a particular metabolic pathway.

 Polycistronic mRNA vs Monocistronic mRNA

Polycistronic mRNA 

1. Contains codons of a more than one cistron.
2. Codes only for more than one protein.
3. Is transcribed from a more than one gene (cistron) and has as many as initiation and termination codons.
4. Present in prokaryotes.


Monocistronic mRNA

 POLYCISTRONIC
1. Contains codons of a single cistron.
2. Codes only for a single protein.
3. Is transcribed from a single gene (cistron) and has one initiation and termination codon.
4. Present in eukaryotes.
