HOW can you be a good steward of your epigenome? At the heart of epigenetics is the realization that environmental influences can turn on and off genes. Conventional biology describes that our inheritance is set in stone at conception when the egg and sperm fuse, where genes remain unchanged and experiences are never inherited. However, epigenetics challenges this view. Describe how! Give specific examples.

How does the presence of stress and/or poor nutrition in a pregnant woman affect her child and future generations?

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
