Quizplus · Accepted Answer

The addition of methyl groups to DNA, a process known as DNA methylation, can lead to mutations. This is because methylation can alter gene expression and potentially cause errors during DNA replication or repair, leading to mutations. Tobacco chemicals are known to induce such methylation changes, contributing to the mutagenic effects of tobacco.
