Dna methylation

Dna methylation

(Science: molecular biology) process by which methyl groups are added to certain nucleotides in genomic dna.

this affects gene Expression, as methylated dna is not easily transcribed. The degree of methylation is passed on to daughter strands at mitosis by maintainance dna methylases. Accordingly, dna methylation is thought to play an important developmental role in sequentially restricting the transcribable genes available to distinct cell lineages.

in bacteria, methylation plays an important role in the restriction systems, as restriction enzymes cannot cut sequences with certain specific methylations.

Re: DNA Methylation

Thanks- this is really interesting. I couldn't though find a good definition of hemimethylated by doing a Google search. Do you happen to know of somewhere where I could find the definition?

DNA Methylation

How does DNA methylation occur- is there an enzyme that carries out the methylation? How is it regulated?
