• A segment of DNA that encodes for a protein
• Your genome

The difference between DNA code and the epigenome is that the DNA code is

• flexible, while the epigenome is fixed for life
• fixed for life, while the epigenome is flexible
• determined by the environment, while the epigenome is not
• determined by one's stress level, while the epigenome is not

At which stage in the lives of identical twins is the DNA code expected to be most similar?

• Age 6 months
• Age 21
• Age 55
• Trick question; the DNA code doesn't generally change

At what stage in the life of identical twins is the epigenome expected to be most similar?

• Age 6 months
• Age 21
• Age 55
• Trick quesiton; the epigenome never changes

Which factor can affect the epigenome?

• nutrition
• exercise
• stress 
• all of these factors can affect the epigenome

What is a Gene?

• A segment of RNA that encodes for a protein
• A chromosome
• A segment of DNA that encodes for a protein
• Your genome

A chemical modification of DNA that does not affect the nucleotide sequence of a gene but makes that gene less likely to be expressed.

• methylation
• acetylation
• transcription
• translation
