Which of the Following is the Most Common Place to Find

Question

Which of the following is the most common place to find DNA methylation?
A)on guanines when adjacent to cytosines
B)on guanines when adjacent to other guanines
C)on cytosines when adjacent to guanines
D)on cytosines when they are base paired to guanines
E)on cytosines when adjacent to other cytosines

Accepted Answer

DNA methylation is most commonly found on cytosines when they are adjacent to guanines, occurring in the context of CpG dinucleotides. This pattern of methylation is frequently associated with gene silencing and has important implications in development and disease.
