CBSEENBI12047039

Assertion : Replication and transcription occur in the nucleus but translation occurs in the cytoplasm.

Reason : mRNA is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.

  • If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion

  • If both Assertion and Reason are true but the Reason is not the correct explanation of the assertion

  • If Assertion is true but Reason is false

  • If both Assertion and Reason are false

Solution

A.

If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion

DNA replication is the process of forming a copy of DNA. Transcription is the formation of RNA over DNA template. They both occur in nucleus as the required material DNA and RNA are present in the nucleus.

Translation is the process of protein synthesis. 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.
