Define epigenetics

Without altering the DNA base itself, epigenetics is the analysis of how certain epigenetic factors can alter the expression of the gene.
Without altering the epigenome itself, epigenetics is the analysis of how certain epigenetic factors can alter the expression of the gene.
Without altering the DNA base sequence itself, epigenetics is the analysis of how certain environmental factors can alter the expression of the epigene.

How does sleep deprivation lead to obesity?

By manipulating genetic factors, which consequently lead to obesity
By creating a hormonal imbalance to the hormones which regulate hunger and appetite
By manipulating epigenetic factors, which consequently lead to obesity
By manipulating environmental factors, which consequently lead to obesity
By creating a neural imbalance to the neurones which regulate hunger and appetite

9

Can gene therapy be used to treat obesity levels in the near future?

Yes if only it is able to correct the obesity phenotype in the long term
No gene therapy is illegal
No it has not yet been shown to work
Yes of course. There is no problem, except for the fact it is expensive
No, the risks outweigh the benefits of using gene therapy

10

Can DNA methylation be used to treat obesity?

No, it has been shown not to work
No, it is too difficult to methylate DNA. Too expensive as well.
Yes, there is no problem with using it.
Yes it is being used right now.
Yes DNA methylation can be used as there are no side effects involved.
