Stem cells and cloning techniques

Why are stem cells so important to medical researchers?

• They are the only potential treatment for Parkinson's and Alzheimer's disease

• They may have the ability to target and destroy specific cancer cells

• In most countries in the world, stem cell use is illegal

• They may be used to create perfectly matched tissue to treat an individual disease or disorder

When creating a cloned mammal, what structure contains the genetic information the scientist intends to clone?

• blastocyst

• enucleated oocyte

• surrogate mother

• somatic cell

The first reports of successful mammal cloning date to the:

• 18th century.

• 19th century.

• 20th century

• 21st century

Which structure has the potential to develop into any other cell within the human body?

• totipotent cell

• zygote

• somatic cell

• ovum

Pluripotent stem cells (iPS cells) are reprogrammed adult cells produced in a lab to take on characteristics of which type of stem cell?

• somatic stem cells

• tissue-specific stem cells

• embryonic stem cells

• mesenchymal stem cells

Somatic stem cells are undifferentiated cells that are also called:

• embryonic stem cells.

• adult stem cells.

• totipotent stem cells.

• zygote stem cells.

Which stem cells are most often used to avoid rejection by the patient's immune system?

• adult stem cells

• therapeutic stem cells

• synthetic stem cells

• cloned stem cells

Reproductive cloning is also called:

• adult stem cell transfer.

• somatic cell nuclear transfer.

• nucleic acid recombination.

• protein synthesis.

What animal was successfully cloned in a research facility in Scotland in 1996 from an adult stem cell?

• dog

• lizard

• chicken

• sheep

What Stem cells give rise to the cell types needed from the tissues from which they are derived?

• Pluripotent stem cells

• Totipotent stem cell

• Somatic stem cells

• IPSC stem cells
