CpG dinucleotides refer specifically to the sequence of cytosine (C) followed by guanine (G) in DNA, with the 'p' indicating the phosphate group that connects the two nucleotides. This structure is crucial for understanding DNA methylation, a key epigenetic mechanism that regulates gene expression. The discussion highlights the simplicity of the concept while emphasizing its importance in molecular biology.
PREREQUISITESMolecular biologists, geneticists, and researchers interested in epigenetics and gene regulation will benefit from this discussion.
