DNSmetilációval
DNSmetilációval is a biological process that involves the addition of a methyl group to a DNA molecule. This epigenetic modification plays a crucial role in gene regulation and is essential for various cellular functions, including development, differentiation, and genomic stability. The primary site of DNA methylation in mammals is the cytosine base, specifically when it is followed by a guanine base, forming a CpG dinucleotide. These CpG sites are often clustered in regions called CpG islands, which are frequently found in the promoter regions of genes.
The methylation of DNA can influence gene expression in several ways. When CpG islands in a gene
DNA methylation is a dynamic process, meaning it can be added and removed throughout an organism's life.
