Final answer:
DNA methylation occurs within specific regions called CpG islands, which can either silence genes with a high frequency of cytosine and guanine dinucleotide DNA pairs (CG) found in the promoter regions of genes. or have other regulatory effects. Methylation patterns can be influenced by environmental factors and can be heritable.
Step-by-step explanation:
DNA methylation occurs within specific regions called CpG islands, which are stretches with a high frequency of cytosine and guanine dinucleotide DNA pairs (CG) found in the promoter regions of genes. The cytosine member of the CG pair can be methylated, and this modification affects gene expression. Methylation can either silence genes or have other regulatory effects. Methylation patterns can be influenced by environmental factors, such as parental diet, and can be heritable.
