Epigenetics

What is epigenetics?

• The study of how behavior and environment change our gene expression

• The study of how DNA changes

• The study of genes

• The study of RNA and DNA and how they translate

DNA reacts with molecules in the cell that activate or deactivate genes

• True

• False

What is a genome?

• a multitude of molecules (chemical compounds and proteins) that tell the genome what to do

• the entire set of genetic instructions of an organism

• building blocks of protein

• carries hereditary information

What is an epigenome?

• a multitude of molecules (chemical compounds and proteins) that tell the genome what to do

• complete set of genetic material in an organism

• ability of one genotype to produce more than

  one phenotype

• building blocks of protein

Epigenetic changes can either boost or interfere with transcription of a gene

• True

• False

What are the causes for epigenetic changes?

• Diet

• Chemical Exposure

• Meditation

• Social Experiences

• All of the Above

An environment cannot affect your genetic expression.

• True

• False

If DNA is more tightly wound, what happens?

• RNA polymerase can’t bind as easily-> less transcription-> inactive gene

• RNA polymerase can’t bind as easily-> less transcription-> Active gene

• RNA binds easier—> less transcription—> inactive gene

• RNA binds easier—> more transcription-> active gene
