Any process that protect an organism from invading foreign DNA by methylation of self DNA at specific sequences and nucleolytic cleavage of unmethylated foreign DNA. The covalent alteration of one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule, resulting in a change in its properties. Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides. The covalent alteration of one or more nucleotide sites in DNA, resulting in a change in its properties.
