  • question_answer
    Assertion : Replication and transcription occur in the nucleus but translating occurs in the cytoplasm. [AIIMS 2005] Reason : mRNA is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.

    A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion

    B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion 

    C) If the assertion is true but the reason is false

It is separated from transcription in both space and time. It prevents the intermixing of raw materials, protect DNA from respiratory enzymes and ribosomal machinery from nuclease.
