Question

In which of the following groups are most mRNAs monocistronic?
A)bacteria
B)archaea
C)eukarya
D)bacteria and archaea
E)All mRNAs are monocistronic.

Accepted Answer

In eukaryotes (eukarya), most mRNAs are monocistronic, meaning they typically carry the information for just one protein. In contrast, prokaryotes (bacteria and archaea) often have polycistronic mRNAs, which contain the information for multiple proteins.
