Answer:
Polycistronic mRNAs
Explanation:
Normally In Eukaryotic cells the messenger RNAs (mRNA) only contain the information to produce a protein, these mRNAs are known as monocistronic.
In Prokaryotes, the transcription system is usually polycistronic, this means that a mRNA have the information to encode two or more genes.
As an interesting example of the co-evolution of Eukaryotes, the mitochondrial genome has polycistronic genes.
There's two ecosystems. A Terrestrial Ecosystem and an Aquatic Ecosystem. Examples of terrestrial ecosystems include the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts. Wetlands, rivers, lakes, and coastal estuaries are all aquatic ecosystems.
