WebRNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA. The ribose sugar of RNA is a cyclical structure consisting of five carbons and one oxygen. WebCpG sites occur with high frequency in genomic regions called CpG islands (or CG islands ). Cytosines in CpG dinucleotides can be methylated to form 5-methylcytosines. …
