Aim: How do scientists clone
organisms?
Hello Dolly!!
What is a Clone?
A clone is an
organism that is
genetically
identical to the
organism from
which it was
produced.
Do the cells of our body make
exact copies of themselves?
Yes
When?
Repair
Growth
What process ensures that the
offspring will be genetically
identical?
DNA
Replication
Cloning vs. Asexual
Reproduction
Cloning is a technique
that accomplishes the
same end result as
asexual
__________reproduction.
What is the end result?
The production of offspring with identical
genetic information as the parent.
Can we clone organisms that
normally reproduce sexually?
Yes, scientists have
been able to
clone animals.
Steps of Cloning:
1)The nucleus from an egg cell is
removed.
2)The nucleus of a body cell from a
donor is removed.
3)The nucleus of the body cell is placed
inside the egg cell.
4)The egg cell with the new nucleus is
placed inside the uterus.
5)When the baby is born, it will have the
same genetic information as the
donor.
Why Clone?
1) Clone Stem Cells
2) Revive endangered or
extinct species
3) Reproducing a
deceased pet
4) Clone humans??
Do you think identical
twins are clones?
Explain. Can you
hypothesize how
identical twins are
formed?
