Operational Genes Found Within the Genome of an Organism Govern

Operational genes found within the genome of an organism govern:

A) translational needs (e.g., elongation factor and peptidyl tranferase)
B) conditional needs (e.g., fermentation and toxin production)
C) ribosomal needs (e.g., rRNA and tRNA)
D) replication needs (e.g., DNA polymerase and DNA helicase)
E) transcriptional needs (e.g., RNA polymerase and sigma factor)
