Question

which outcome occurs after mrna is transcribed?
it leaves the cytoplasm through the cell membrane.
it remains in the nucleus.
it enters the cytoplasm and moves toward ribosomes.
it becomes part of the nucleolus.

Explanation:

• Option 1: mRNA is in the nucleus initially and exits via nuclear pores, not cell membrane, so wrong.
• Option 2: mRNA doesn't stay in the nucleus after transcription; it moves to cytoplasm, so wrong.
• Option 3: After transcription in the nucleus, mRNA enters the cytoplasm and moves to ribosomes for translation, which is correct.
• Option 4: The nucleolus is for ribosome subunit assembly, mRNA doesn't become part of it, so wrong.

Answer:

C. It enters the cytoplasm and moves toward ribosomes.
