6 Questions
What is epigenetics?
Epigenetics is a field that studies how factors above the genome can change gene expression.
What is epigenetics and how can it impact gene expression?
Epigenetics is the study of how factors above the genome can change gene expression. Epigenetic marks can influence gene activity, such as methylation and histone modifications.
What are some examples of epigenetic marks?
Some examples of epigenetic marks include methylation and histone modifications.
How can the environment and diet of a pregnant mouse impact her offspring's gene expression?
The environment and diet of a pregnant mouse can impact the expression of the agouti gene in her offspring.
How can the environment impact gene expression in offspring?
The environment, such as the diet of a pregnant mouse, can impact the expression of genes in her offspring through epigenetic marks.
How can understanding the epigenome help us better understand how our cells and bodies function?
Understanding the epigenome can help us better understand how our cells and bodies function because epigenetic marks can be inherited from cell to cell and from parent to offspring, and can be influenced by both external and internal cues. This knowledge can inform research into medical conditions and potential treatments, such as epigenetic therapy.
