Human-assisted CloningHuman-assisted CloningUnlike simpler animals such as sponges and hydras, more complex animals lose their cloning ability as they become specialized.
Human assistance is required
Humans use all the asexual cloning methods in order to produce desired results with organisms:
Binary fission Budding Fragmentation
Vegetative Reproducition Spore Formation

Reproductive CloningReproductive CloningReproductive cloning: (aka adult DNA cloning)Purpose is to produce a genetic duplicate of an existing or dead organism.
*Not all body cells can be used to make a clone
(some cells are specialized)*
Steps involved:1. Remove nucleus from an egg cell2. A mammary gland cell is removed from an adult
female3. Electricity fuses mammary and egg cell4. Fused cell begins dividing5. Dividing embryo is inserted into surrogate mother

Reproductive CloningReproductive CloningIssues: Only 10% of clones usually survive Surviving clones can be abnormally large and have higher rates of infection and cancerExample:
Dolly (the cloned sheep) died after only 6 years due to lung disease
Average sheep lifespan: 10-12 years)

Therapeutic CloningTherapeutic CloningTherapeutic cloning: used to correct health problems
• Very important to therapeutic cloning are stem cells (cells that can become different types of cells)
• Controversial because the best stem cells are from embryos which are destroyed when harvesting cells
• Stem cells can be used to replace cells damaged from injuries or disease
• Diabetes, spinal injuries, Parkinson’s disease are only a few that can benefit from stem cell therapy

Disagree/Agree/Neutral Disagree/Agree/Neutral ActivityActivity
I will post a controversial statement about cloning. Individually, decide whether you agree, disagree, or are neutral.
Once you decide on your position, move to the designated location.
The ‘Agree’ group will talk together and come up with a joint statement about why they agree with the statement.
The ‘Disagree’ group will do the same thing.
The ‘Neutral’ group will think of 1 question they want to ask the ‘Agree’ and ‘Disagree’ group to help them choose a side.
The ‘Agree’ group and ‘Disagree’ group will make a final statement. The people in the ‘Neutral’ group must then choose a side.

StatementStatement
It is reasonable to spend $155,000 to clone a beloved pet if I have the money and desire to do so.
(remember Lancelot Encore from the video?)

StatementStatement
It is wrong to destroy stem cells from embryos that
are able to develop into an individual/person.

StatementStatement
Human-assisted cloning is an abuse of power – it is not natural, and therefore we
should avoid doing it.

StatementStatement
We should concentrate our efforts on cloning famous
people (ex. Albert Einstein) and extinct animals.

StatementStatement
I would want to have a clone of myself so that there will be a supply of my organs in case any of my organs fail.
