Epigenetics

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

Which factor can affect the epigenome?

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

The complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes.

• genome
• epigenome
• genetic markers
• RNA codon
