Usage: technical; biology; usually used in plural form

Examples

• Nonhistones play a crucial role in regulating gene expression in eukaryotic cells.
• The research team studied how nonhistones interact with DNA to control transcription.
• Unlike histones, nonhistones are more diverse in structure and function.
• Nonhistones include transcription factors and other regulatory proteins.
• The ratio of histones to nonhistones varies depending on the cell type and developmental stage.
