WebCytosine deamination can alter the genome's many regulatory functions; previously silenced transposable elements (TEs) may become transcriptionally active due to the loss of CPG … WebCytosine is, however, obtained in the chemical or enzymatic degradation of nucleic acids. Identification and determination is usually based on the UV absorption spectrum. Cytosine is deaminated to uracil by cytosine deaminase. That reaction is the basis for the specific determination of cytosine.

"WebIt contains a viral genome --- basically a very small and simple chromosome --- together with a polymerase enzyme. Once the virus infiltrates one of your cells, the polymerase enzyme synthesizes mRNA transcripts for each of the genes in its genome. It then commandeers your own ribosomes and uses them to build its own proteins. " - Cytosine is an enzyme that digests proteins
