4. Explain why transcription must occur in the nucleus.



5. Why does a cell need to carry out transcription before translation?

Answers

Answer:

4. Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.

5. Transcription needs to occur before translation because the product of transcription, messenger RNA (mRNA), is the starting material for translation.
