    23. Which correctly differentiates transcription from translation in eukaryotes?
    B. Transcription occurs in the nucleus, while translation occurs in the cytoplasm.
    A. Transcription produces proteins, while translation produces nucleotides.
    D. Transcription makes the conversion from mRNA to trait, and translation makes the conversion from DNA to mRNA.
    C. Transcription utilizes mRNA, tRNA and rRNA, while translation only utilizes DNA and mRNA.

  • Q8
    What explains the changes that occurred between the two biomolecules?
    Question Image
