RNA differs from DNA in that it is usually single-stranded, contains ribose sugar instead of deoxyribose, and uses uracil in place of thymine.

explain what an operon is and how it functions
An operon is a cluster of genes under the control of a single promoter, which allows for the coordinated regulation of gene expression in prokaryotes; it typically consists of structural genes, a promoter, and an operator, enabling the bacteria to efficiently respond to environmental changes.
