Question
Gene regulation in eukaryotes involves reorganization of chromatin structure such that DNA binding is weakened in regions to be transcribed. This is accomplished through chemical modification of histone proteins. enzymatic degradation of histone proteins. release of histone proteins by competition with other nuclear proteins. chemical modifications to the DNA that weaken histone association. release of histone proteins by DNA helicase.

The correct answers are
When cells wants to switch on a gene from chromosome, cytosine are unmethylated or Histones are acetylated, so that dna detaches from Histones and genes can be expressed.
When cell wants to turn off the genes, cytosine of DNA are methylated and histones are deacetylated.
