Question

Quizplus · Accepted Answer

HAT (Histone Acetyltransferases) enzymes are involved in the epigenetic regulation of gene expression, including genes related to memory and learning. By acetylating histones, they enhance the transcription of certain genes, thereby playing a crucial role in the long-term remembering of fear conditioning by making the associated memories more accessible or stable.
