In this chapter, we focused on epigenetic modifications to the genome that regulate gene expression. Several mechanisms are involved, and epigenetic control of gene expression is important in development, cancer, and modulating the genomic response to environmental factors. From the explanations given in the chapter,

What is the evidence that epigenetic changes are involved in cancer?

Video transcript

Hey everyone, Let's take a look at this question together which of the following is lower in cancer cells. So according to research in cancer cells, many investigators showed that complex changes in D. N. A. Methylation patterns are associated with cancer. And research showed that in addition to those DNA methylation patterns. So in addition to those DNA methylation patterns, researchers found that genomic hippo methylation patterns, our property of all cancers examined to date and so of the following, which is lower in cancer cells, is answer choice B. Methylation. Because in those cancer cells, researchers have observed that the cancer cells had much lower levels of methylation, then normal cells derived from the same tissue. And that subsequent research by many investigators showed that complex changes in DNA methylation patterns are associated with cancer. In addition to these genomic hipAA methylation patterns. So, answer choice B is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
