In contrast to histone acetylation, which always correlates with gene activation, histone methylation can lead to either transcriptional activation or repression. How do you suppose that the same modification – methylation- can lead to differing cellular outcomes? Please give me long detailed answer.

Due the presence of the 2' hydroxyl group, RNA is susceptible to degradation. Also, it is mainly single-stranded, which makes it susceptible to degradation by nucleases. It is presumed that some of the ancient RNAs may have developed the capability of methylating other RNAs for their benefit as methylation protect the nucleic acid from degradation.
