What is histone? - Science Query

Webb22 sep. 2024 · The charge of a histone affects its function by influencing the way it binds to DNA and other histones. Histones with a positive charge bind more tightly to DNA than those with a negative charge. This can influence the accessibility of DNA to the enzymes that regulate gene expression.
