Homework Answers
22. Prokaryotic transcription occurs in the cytoplasm alongside translation. Prokaryotic transcription and translation can occur simultaneously. Therefore translation and transcription are coupled.
23. In eukaryotes, transcription occurs in a membrane-bound nucleus while translation occurs outside the nucleus in the cytoplasm. Therefore, translation and transcription are uncoupled.
24. Transcription is the process by which the information in DNA is copied into messenger RNA (mRNA) for protein production.
25. Translation is the process in which ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus.

Question 15 1 pts The most significant influence on why mRNA is processed differently in prokaryotes than in eukaryotes is the fact that eukaryotes separate transcription and translation because these organisms have a nucleus. eukaryotes are multicellular organisms. O prokaryotes do not add a poly(A) tail. prokaryotes are often polycistronic. Question 16 1 pts Which is true of RNA polymerases in both prokaryotic and eukaryotic organisms? They have the same number of cofactors in prokaryotes and eukaryotes. They are composed...
