Genes that are transcribed together as a single unit in prokaryotes are found on dna segments called

Operon is the DNA segments with transcribed genes as single unit.

An operon is a bunch of practically related genes that are constrained by a common administrator. Operon comprise of different genes gathered with a promoter and an operator. Operon are available in prokaryotes (microbes and archaea), however, they are missing in eukaryotes.

In certain circumstances, numerous operon are constrained by the equivalent administrative protein; in these cases, the operon structures a regulon. Operon was first distinguished as a method of quality articulation control in 1961 by François Jacob and Jacques Monod.

ur answer is e & d

explanation:

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
