Assertion : Replication and transcription occur in the nucleus but translation occurs in the cytoplasm.
Reason : is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion
Step-by-step solution
DNA replication is the process of forming carbon copy of DNA. Whereas transcription is the formation of RNA over DNA template. DNA replication and transcription takes place 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.
