Both the lacY and lacZ gene products are mutually encoded by a single mRNA. Is this condition also found in eukaryotes? What is an advantage of this configuration?
No in Eukaryotes one gene encoding for doesn't have operons that encode for multiple proteins. Rather Eukaryotic mRNA undergoes alternate splicing which results in different protein from the same mRNA.
Many genes are involved in biosynthetic pathways of a compound. If all the genes are not present in one operon then it will be difficult for the cell to regulates all genes. if all the genes are present in an operon like lac operon or trip operon then it will be easy to regulate the expression of genes as the condition required for their expression.
