Concept explainers
To draw: The molecular formula of the covalently modified histone side chain of methyllysine and methylarginine.
Introduction: Covalent modifications of histone side chains consisting of N-terminal tails regulate the interaction with other proteins. The two covalent modifications commonly affecting side chains are acetylation and phosphorylation that are reversible changes. Another modification includes methylation that results in stable and reversible changes.
To explain: How the covalent modifications alter the chemical properties of the histone side chains.
Introduction: Covalent modifications of histone side chains consisting of N-terminal tails regulate the interaction with other proteins. The two covalent modifications commonly affecting side chains are acetylation and phosphorylation. These are reversible changes and effectively modulate the response to environmental changes. Another modification includes methylation that results in stable and reversible changes.
