Once Researchers Identified DNA as the Molecule Responsible for Transmitting

question 31

Multiple Choice

Once researchers identified DNA as the molecule responsible for transmitting heritable traits, they asked how information was transferred from the DNA in the nucleus to the site of protein synthesis in the cytoplasm. Which of the following statements correctly describes the mechanism of information transfer in eukaryotes that accomplishes this task?

• A) DNA from a single gene is replicated and transferred to the cytoplasm, where it serves as a template for protein synthesis.
• B) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.
• C) Histone proteins in the chromosomes transfer information from the nucleus to the ribosome, where protein synthesis takes place.
• D) Transfer RNA takes information from DNA directly to a ribosome, where protein synthesis takes place.
