What has a cell membrane

.
Bacteria are extremely efficient organisms. Which one of the following characteristics describes this efficiency in relation to protein production?
1)Bacteria are polycistronic and have multiple different genes on one mRNA.
2)Every gene is always turned on so that proteins are produced at a rapid rate.
3)Bacteria have multiple different types of polymerases for each gene.
4)Every gene has an activator that is necessary to begin translation so the cell doesn’t waste energy producing unnecessary proteins.
