CpG Islands are Associated with Which of the Following

Question

CpG islands are associated with which of the following?
A) nucleosome location
B) DNA methylation
C) steroid hormone activity
D) termination of translation

Accepted Answer

CpG islands are areas of DNA rich in cytosine and guanine nucleotides, which are often located near the start site of genes. These regions are often associated with DNA methylation, which is the addition of a methyl group to the cytosine nucleotide. DNA methylation can affect gene expression and the formation of nucleosomes, but it is not specifically associated with steroid hormone activity or termination of translation.
