WebNov 9, 2015 · The cytosine bases in a genome can be modified to 5-methylcytosine by adding a methyl group at the 5′ position. This process, called DNA methylation, is conserved from algae to animals and plants (1, 2).DNA methylation can be separated into different types based on the local sequence context. WebMar 28, 2008 · Author SummaryGenes are packaged into chromatin by a variety of specialized proteins. Many different types of chromatin exist, and each may regulate gene expression in different ways. It was previously observed that neighboring genes are sometimes packaged together into a single type of chromatin, which can facilitate their …
