What can you conclude from the fact that humans have cloned plants for thousands of years?
Most of the crops that exist today are clones
Cloning plants is much easier than cloning animals
Cloned plants are immune to all diseases and pests
Much of today's modern technology was developed in ancient times
Clones have the exact same:
Personalities
Physical appearances
Intelligence levels
Genetic material

2
1
0
Why would scientists want to clone cows?
To produce more cows at a faster rate
To produce adult cows instead of calves
To produce stronger and healthier livestock
To replace chickens and goats, which are harder to clone
How might cloning eventually help humans live longer?
Clones tend to live longer than the parent organism
Cloned human organs could replace unhealthy ones
By being cloned multiple times, a person could essentially live forever
The food obtained from cloned organisms would be healthier than ordinary food
How did Dolly compare to sheep that were cloned with the same DNA?
Dolly lived longer
Dolly had more genetic material
Dolly was less healthy
Dolly had fewer parents
Which of the following is an ethical question about cloning?
Can a human clone ever lead a fulfilling life?
How can DNA be removed from adult animal cells?
What will happen to crop yields if cloned plants develop a virus?
Is human cloning scientifically possible?
This diagram shows .............................................. process.
cloning
regeneration
Why did it take three sheep to create one clone?
One sheep donated DNA, another donated an egg cell, and a third carried Dolly in her womb.
The sperm and egg cells of two sheep were combined,and implanted in the womb of a third sheep.
Scientists combined different pieces of DNA from three separate sheep.
Two fertilized eggs were implanted into the wombs of two sheep, but only one matured properly.
In the term "nuclear transfer," the word "nuclear" refers to:
The source of power used to clone animals.
The cell nucleus.
The atomic nucleus.
The familiar relationship between clones.
