1. How do scientists clone organisms?
Hello Dolly!!

2. 1) What is a Clone? A clone is an organism that is genetically
identical to the
organism from which it
was produced.

3. 2) Do the cells of our body make exact copies of themselves?
Yes.
When?
Repair
Growth

4. 3) What process ensures that the offspring will be genetically identical?
DNA Replication

5. 4) Asexual Reproduction:
X X
X X
Parent
Offspring
X X
Genetic Information
(DNA)
a) How many parents?
b) How does the genetic
Information between the
parent and offspring
compare?

6. 5) Cloning vs. Asexual Reproduction
Cloning is a technique
that accomplishes the
same end result as
__________reproduction.
asexual
What is the end result?
The production of offspring
with identical genetic
information as the
parent.

7. 6) Can we clone organisms that normally reproduce sexually?
Scientists have recently
been able to clone
animals.

8. How is this done?

9. 7) Steps of Cloning: The nucleus from an egg cell is removed.
The nucleus of a somatic cell from a donor is
removed.
The nucleus of the somatic cell is placed inside
the egg cell.
The egg cell with the new nucleus is placed inside
the womb.
When the baby is born, it will have the same
genetic information as the donor.

10. 8) Why Clone? 1) Clone Stem Cells 2) Revive endangered or
extinct species
3) Reproducing a
deceased pet
4) Clone humans??

11. 9) How are Identical Twins Formed?
Fertilization
Mitosis +
Sperm
Egg
Zygote
Twin #1
Twin #2

12. 10) Why do Identical Twins look alike?
After the cell is fertilized, it begins
to divide by mitosis.
Zygote
Therefore the genetic
information is identical
in each of the cells.

13. 11) How are Fraternal Twins Formed?+
Sperm
Egg
Zygote +
Sperm
Egg
Zygote

14. 12) Why do Fraternal Twins look different?
They are formed from two
different sperm and two
different eggs.
Zygotes
