C) RNA<span> carries the code from DNA in the nucleus to the ribosome for protein synthesis.
The ribosomes are in the cytosol/cytoplasm, but DNA is in the nucleus. DNA is too large to travel out of the nucleus, so it needs the help of mRNA to transfer the genetic code to the ribosome, which translates the code into a protein. That means A, B, and D cannot be true. </span>
