Dna methylation promotes what other chemical alteration of chromatin to suppress gene expression? histone deacetylation histone phosphorylation histone ubiquitylation dna phosphorylation dna ubiquitylation

The correct answer is histone deacetylation.  
The DNA methyltransferase and proteins that bind to methylated DNA are associated with histone deacetylase. Those proteins form complexes with the proteins involved in deacetylation of histones and therefore, when DNA is methylated, nearby histones are deacetylated, which results in repression of transcription. 

I’m not exactly sure what your trying to ask, but if it’s how an organelle is similar to a body system or a part a nucleus is like a in function. but i don’t fully understand what you’re trying to ask
