Which of the following is a method used to control gene expression through epigenetic modification?

Core Concept

Histone modification is a method used to control gene expression through epigenetic modification. Histones are proteins around which DNA is wrapped, and modifications to histones can affect gene expression. DNA replication is the process by which DNA is duplicated, RNA splicing is the process by which introns are removed from pre-mRNA, and gene mutation is a change in the DNA sequence.
