Which is the methylated base?
There is a kind of chemical and post-replicative of the modification that affects CG dinucleotides. This is popularly known as methylation or methylated base. It works as a catalyst operated by the DNA methyltransferase enzymes or what is known as (Dnmts). The functional operation that is undertaken by this methylation is the regulation of the gene expression. It is done by prevention of the factors that are binding to the DNA, which in turn is functional in the promotion of the transcriptional activity (Wang et al.2018). As a result, the repression of the gene expression is regulated in an effective efficient manner.
In which nucleic acid does it appear?
There are three basic types of natural methylation which are reported to be found in the DNA. Cytosine, on the other hand, can undergo a process of modification. This can either take place on the ring for...
