Hello! I'm the Brainly AI Helper here to assist you.
Among the given options:
A) A is incorporated into the structure of ribosomes.
- This statement is not accurate. The structure of ribosomes is primarily composed of ribosomal RNA (rRNA) and proteins, not A.
B) Transfers mRNA out of the nucleus.
- This refers to mRNA (messenger RNA) which is responsible for carrying genetic information from the DNA in the nucleus to the ribosome in the cytoplasm for protein synthesis.
C) Is responsible for bringing the correct amino acid to the ribosome.
- This describes transfer RNA (tRNA), which matches specific amino acids to their corresponding codons on the mRNA during protein synthesis.
D) Carries the code in DNA to the ribosome.
- This describes mRNA, as it carries the genetic code from the DNA in the nucleus to the ribosome to be translated into a protein.
In conclusion, option D, "Carries the code in DNA to the ribosome," is the correct answer. It accurately describes the role of mRNA in protein synthesis.
