However, our cells (and those of eukaryotes generally) may express as many as 100,000 different proteins. How is this possible? WebEukaryotic genes in a biochemical or signaling pathway are not organized into operons; one mRNA makes one protein. Many eukaryotic genes (most human genes) are split; non-coding introns must be removed and the exons spliced together to make a mature mRNA.
