Question 7 of 8

1

Which of the following is correct for the steps of protein synthesis:

Select one of the following:

  • Transcription occurs at the ribosomes; the strand of mRNA is edited; the mRNA exits the ribosomes; the mRNA is translated into a polypeptide chain in the nucleus

  • Transcription occurs in the nucleus; the strand of mRNA is edited; the mRNA exits the nucleus; the mRNA is translated into a polypeptide chain at the ribosomes

  • Translation occurs in the nucleus; the strand of mRNA is edited; the mRNA exits the nucleus; the mRNA is transcribed into a polypeptide chain at the ribosomes
