Quote by Alfred Hershey

"The gene is the unit of selection, the level at which natural selection operates most effectively."

"We are all survival machines for our genes."

"Bacterial genetics opened up the entire field of molecular biology."

"The phage group changed everything we thought we knew about heredity."

"Faith guides me through difficult times."

"Faith is believing when you can't see."

"You have to believe in something, or you'll fall for anything."

"Faith in God and in each other is what sustains us"
