More Information
DNA is crucial for storing the genetic blueprint of living organisms, whereas RNA acts as a messenger in decoding this blueprint into functional proteins. Understanding the distinction between their structures and functions is vital in molecular biology.
Tips
A common mistake is confusing the nitrogenous bases of DNA with those of RNA. Remember, DNA uses thymine and not uracil, which is found in RNA.
