Cloning and Stem Cells Jeopardy!

Waterford Union High School

Rules

• Each team sends one person per turn. They cannot get help from their team

• First to “buzz” in gets 15 seconds to answer. • If the first person to buzz cannot get the answer, the

second team can buzz in. Once they buzz in, they too have 15 seconds. They also cannot get help.

• You either gain or lose points on each turn.• If no team buzzes within 10 seconds, the question

ends and the answer is given.

This & That

Early Experiments

• This researcher tied a salamander zygote in half to show that cells did not lose DNA as they divided.

• Spemann

Early Experiments

• These researchers moved frog egg nuclei from one cell to another.

• Briggs & King

Early Experiments

• This researcher moved an adult frog nuclei from the intestinal cells to an enucleated egg to create the first cloned animals.

• Gurdon

Early Experiments

• This was the first cloned mammal• Dolly the Sheep

Early Experiments

• 277

Stem Cells

• This is the kind of stem cell found in your body right now

• Adult or somatic stem cells

Stem Cells• This kind of stem cell comes from a blastocyst

• Embryonic stem cell

Stem Cells

• This kind of stem cell is pluripotent• Embryonic Stem Cell

Stem Cells

• This kind of stem cell has the lowest risk of rejection after transplant

• Adult stem cell

Stem Cells

• This kind of stem cell is illegal• None

Cells & Stuff

• This is a fertilized egg. • Zygote

Cells & Stuff

• These are the “caps” at the end of a chromosome.

• Telomeres

Cells & Stuff

• This is what happens to telomeres as cells age• They shorten

Cells & Stuff
