Describe how methylation occurs on newly replicated DNA

Expert Solution

Answer.) DNA methylation in bacteria is regularly thought of in its part to shield DNA from limitation endonucleases. Notwithstanding this part, be that as it may, thinks about in Escherichia coli, Salmonella enterica serovar Typhimurium (alluded to as S. enterica from this point forward) and Caulobacter crescentus have demonstrated that methylated bases have other biological capacities. In these cases, the methylated bases are not some portion of a limitation/adjustment framework and the chemicals that create them are frequently alluded to as orphan or singular DNA methyltransferases. The postreplicative DNA methylation created by these catalysts superimposes on the essential DNA sequence optional data that has hugeness for DNA exchanges, for example, translation, transposition, start of chromosome replication, mRNA usage and counteractive action of transformations by DNA repair. These alterations are realized in two ways, the first being essentially an adjustment in the consistent state level of the methyltransferase either up or down from ordinary. The second mechanism is through the setup of the nucleotide sequence subject to methylation; it can exist as symmetrically methylated, unmethylated or two conceivable hemi-methylated courses of action.
