Based on the section 'Genetic information storage and transmission,' what is the correct flow of genetic information for protein synthesis?

  • A: Ribosomes in the nucleus contain DNA instructions for synthesizing proteins.
  • B: DNA in the nucleus contains instructions, and ribosomes are the sites where these instructions are used to make proteins.
  • C: Proteins in the ribosomes contain instructions for making DNA in the nucleus.
  • D: The nucleus synthesizes proteins directly from DNA, while ribosomes break down proteins.

Explanation

The text states 'DNA in the nucleus contains instructions for making proteins' and 'Ribosomes are the sites of protein synthesis.' This directly indicates that instructions from DNA in the nucleus are carried out by ribosomes to make proteins.
