RNA and DNA Flashcard

Front

Which of the following statements best describes the role of RNA in relation to DNA?
Options:
1. RNA is more important than DNA in coding for traits.
2. RNA serves as a messenger to carry genetic information from DNA to the ribosomes.
3. RNA is only found in prokaryotic cells.
4. RNA does not play a role in protein synthesis.

Back

RNA serves as a messenger to carry genetic information from DNA to the ribosomes.
