Growth protocol Logarithmic yeast cells were grown in YPR medium and arrested with alpha-factor together with addition of 2% galactose to induce site-specific recombination of native replication origin chromatin domains. Cells were harvested and frozed for subsequent affinity purification.
Extracted molecule genomic DNA
Extraction protocol Cell pellets were lysed with dry ice in a commercial coffee grinder and chromatin domains affinity-purified as described in the manuscript. The purified chromatin circles were then treated with the M.CviPI/M.SssI (GpC/CpG-5-methyl-Cytosine-specific) and EcoGII (methyl-6-Adenine-specific) DNA methyltransferases. Methylated DNA was then isolated using Phenol-chloroform extraction. EcoGII (methyl-6-Adenine-specific) DNA methyltransferases,

Data processing Base- and modified basecalling were performed with megalodon (v2.3.3) and guppy (v5.0.11) using the res_dna_r941_min_modbases-all-context_v001 model and default parameters.
ARS sequences derived from genome build/assembly Saccharomyces_cerevisisae.R64-1-1 targeted for affinity purification, an in vitro assembled nucleosomal array of 12x601 sequences and a spike-in naked plasmid DNA added in the experiments served as spike-in controls to normalize for methylation efficiencies.
Assembly: Saccharomyces_cerevisiae.R64-1-1
Supplementary files format and content: comma separated files that contain binary information about methylation
