The actual process of chromatin remodeling in eukaryotic cells does not involve:

Out of the following given choices:

HDACs

DNA methylation.

protein kinase cascades.

Histone acetylation.

All of the above are involved in the process known as chromatin remodeling.

The answer is 'All of the above are involved in the process known as chromatin remodeling'. Chromatic remodeling is critical in the regulation of genes on the chromosomes. DNA and histone methylation mostly cause the downregulation of genes due to their compaction hence unavailing them for transcription by RNA polymerases
