Epigenetics

Front

What is epigenetics?

Back

The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself.

Front

True or False: Epigenetic changes are permanent.

Back

False

Front

What is the difference between DNA code and the epigenome?

Back

The DNA code is fixed for life, while the epigenome is flexible.

Front

What are histones?

Back

Protein molecules around which DNA is tightly coiled in chromatin.

Front

What does the term 'epigenome' refer to?

Back

The chemical compound modifications to the DNA code that can tell the DNA code what to do.

Front

Can environmental factors influence the epigenome?

Back

Yes, environmental factors can lead to changes in the epigenome.

Front

What is a common example of an epigenetic change?

Back

DNA methylation, which can silence gene expression.

Front

How do epigenetic changes affect gene expression?

Back

They can turn genes on or off without changing the DNA sequence.

Front

What role do histones play in gene regulation?

Back

Histones help package DNA into a compact form and can influence gene accessibility.

Front

What is the significance of studying epigenetics?

Back

It helps us understand how genes are regulated and how environmental factors can affect health.
