DNA methylation is a biological process by which a methyl group is added to a DNA nucleotide. The purpose of DNA methylation is...
In order to protect the bacterial genomic DNA from its own restriction enzymes, bacterial cells employ a system, wherein methyl transferases methylate certain bases on the DNA â¦ sequence, making them unrecognizable to the restriction enzymes. Each restriction enzyme has a methylase associated with it on the chromosome. This methylase puts methyl groups on the host DNA, and the restriction enzyme doesn't recognize its recognition sequence when it is so methlyated. The host DNA is thus protected from the actions of its own restriction enzyme.
