Epigenetics

Front

What is a Gene?

Back

A segment of DNA that encodes for a protein.

Front

What is a Genome?

Back

The complete instructions for making an organism, consisting of all the genetic material (DNA + its set of Genes).

Front

What can be affirmed according to epigenetics?

Back

Gene expression patterns can be passed down to generations.

Front

What is Epigenetics?

Back

The study of changes in gene activity (that do not involve alterations in the genetic code & are also inherited).

Front

What are Histones?

Back

Protein molecules around which DNA is tightly coiled in chromatin.

Front

What is the Epigenome?

Back

The complete set of epigenetic modifications on the genetic material of a cell.

Front

What role do environmental factors play in epigenetics?

Back

They can influence gene expression without changing the DNA sequence.

Front

What is DNA methylation?

Back

A process by which methyl groups are added to the DNA molecule, affecting gene expression.

Front

What is an example of an epigenetic change?

Back

Changes in gene expression due to diet, stress, or toxins.

Front

How can epigenetics affect health?

Back

Epigenetic changes can lead to diseases such as cancer by altering gene expression.
