Histone modification

is fixed; once a histone is modified it stays that way and the genes with which it is associated are turned on or off permanently

is fixed, but this has no effect on whether genes are expressed

is random- sometimes the lysines are modified and sometimes they're not, but the state is independent of the environment or cell types

can change over time in response to environmental clues, allowing genes to be turned on or off as needed
