प्रश्न
State the difference between the structural genes in a Transcription Unit of Prokaryotes and Eukaryotes.
Advertisements
उत्तर १
In prokaryotes, the structural genes are polycistronic and continuous, whereas in eukaryotes, the structural genes are monocistronic and split.
In prokaryotes, there is a single DNA-dependent RNA polymerase which synthesises all the types of RNAs (mRNA, tRNA and rRNA), whereas eukaryotes have three RNA polymerases − Pol I, Pol II, and Pol III − to synthesise different types of RNAs.
