Explanation:
Capping of hnRNA:
- The process of adding a modified nucleotide (menthyl guanosine triphosphate) to the 5' end of hnRNA is known as capping.
- This modification protects the mRNA from degradation and helps in the recognition of the mRNA by ribosomes during translation.
Function of capping:
- The capping of hnRNA is essential for the proper processing and translation of mRNA.
- It also plays a role in regulating gene expression and facilitating the export of mRNA from the nucleus to the cytoplasm.
Importance of capping:
- Capping helps in the stability of mRNA by protecting it from exonuclease degradation.
- It also assists in the initiation of translation by providing a recognition signal for ribosomes.
Therefore, in the given question, the addition of menthyl guanosine triphosphate to the 5' end of hnRNA is a part of the capping process, which is crucial for the proper functioning of mRNA in gene expression.

At 5' end of hnRNA, a cap is formed by modification of GTP into 7-methyl guanosine or 7m(Gppp). This process is called capping and it protects the mRNA from degradation by nucleases and also.
