Step 1I'll solve this problem by explaining the role of RNA as a messenger and why DNA cannot directly provide genetic instructions to protein-synthesizing machinery.
Step 2: Understanding DNA's Location
- DNA is located in the nucleus of eukaryotic cells - DNA contains genetic instructions but cannot leave the nucleus directly - Proteins are synthesized in the ribosomes, which are located in the cytoplasm
Final Answer
1. Overcome the nuclear membrane barrier 2. Provide a mobile, disposable copy of genetic instructions 3. Enable efficient protein synthesis in the cytoplasm
