The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Concept of Capping:** - Capping is a process that occurs during the maturation of RNA, specifically in the modification of heteronuclear RNA (hnRNA) into mature mRNA. 2. **Identifying the Components of Capping:** - During capping, a specific molecule is added to the 5' end of the RNA. This molecule is known as 5' methyl guanosine triphosphate. 3. **Function of the Cap:** - The addition of the 5' methyl guanosine cap serves a protective function. It prevents degradation of the RNA molecule and helps in the stability and transport of mRNA. 4. **Final Answer:** - In capping, **5' methyl guanosine triphosphate** is added to the **5' end of hnRNA**. ---
