DNA methylation, histone variant, histone modifications, and nucleosome positioning are pathways for epigenetic regulation in eukaryotes. Bacteria, on the other hand, lack histones and nucleosomes; hence, they primarily use DNA methylation as their epigenetic gene regulation. There are three different types of DNA methylation in bacterial genomes: N4-methylcytosine (4mC), N6-methylade... https://www.cd-genomics.com/microbioseq/blog-epigenetics-sequencing-for-studying-bacterial-methylation.html
