Multiple Choice

PRACTICE: Why can prokaryotes perform transcription and translation simultaneously while eukaryotes cannot?

Because in prokaryotes, transcription and translation both occur in the cytoplasm.

Because in eukaryotes, transcription and translation do not occur in the same location within the cell.

Because prokaryotes have polycistronic mRNA while eukaryotes have monocistronic mRNA.

Because prokaryotes use sigma factors while eukaryotes use transcription factors.

Verified step by step guidance

Understand the basic difference between prokaryotic and eukaryotic cells: Prokaryotic cells lack a nucleus and other membrane-bound organelles, while eukaryotic cells have a nucleus where transcription occurs.

Recognize the location of transcription and translation in prokaryotes: Both processes occur in the cytoplasm, allowing them to happen simultaneously.

Identify the location of transcription and translation in eukaryotes: Transcription occurs in the nucleus, and translation occurs in the cytoplasm, preventing simultaneous occurrence.

Consider the type of mRNA: Prokaryotes often have polycistronic mRNA, which can encode multiple proteins, while eukaryotes typically have monocistronic mRNA, encoding a single protein.

Evaluate the role of factors: Prokaryotes use sigma factors for transcription initiation, whereas eukaryotes use a variety of transcription factors, which is not directly related to the simultaneous occurrence of transcription and translation.
