A: Yes. Eukaryotes and prokaryotes have coding regions and non-coding regions. However, there is a difference, that is, the exons in the coding region of eukaryotes are discontinuous and divided by introns. Both introns and exons belong to the coding region, and mRNA is transcribed by exons, while the coding region of prokaryotes only has exons without introns, so the coding region is continuous.

Helicobacter pylori can synthesize external substances into its own organic matter in acidic environment, so is its assimilation type autotrophic?

A: No, Helicobacter pylori is heterotrophic. A key criterion to distinguish autotrophic from heterotrophic is whether inorganic matter can be used to synthesize organic matter for growth and development. Helicobacter pylori can't use inorganic substances to synthesize organic substances. It uses only simple small molecular organic substances, and then converts the small molecular organic substances into its own needs through the action of enzymes, which is equivalent to saprophytes, not autotrophs.
