The idea of cloning animals
was presented by _____ in 1938.
Spemann
Therapeutic cloning
successfully addresses the key problem of ________________, which must be
solved before embryonic stem cells can be used to repair damaged human organs.
Immune acceptance
In therapeutic cloning, why
are the embryonic cells used to treat an individual not rejected by that
individual?
Because the embryonic cells
are cloned from the same individual they are injected into
At what point does the U.S.
Supreme Court take the position that human life begins?
When independent survival
is possible
If a gene has been
methylated:

The cloning of
"Dolly" established that cloning an adult animal cell is possible.
This is called:
Reproductive cloning
Why were gene therapy
trials to treat severe combined immunodeficiency disease (SCID) halted in 2005?
Some of the treated
children in the trial developed cancer.
Ian Wilmut successfully
cloned Dolly the sheep from a fully differentiated sheep cell. This type of
cloning is known as:
Reproductive cloning
An adult stem cell differs
from an embryonic stem cell in that it is not:
Pluripotent
A clear distinction between
therapeutic cloning and reproductive cloning is that:
Therapeutic cloning
involves the eventual destruction of the embryo, whereas reproductive cloning
does not
Scientists in Scotland
figured out a novel method to clone cells successfully. It involved:
Using an egg and a nucleus
that were at the same stage of the cell cycle
Adult stem cells are just
as totipotent as embryonic stem cells.

therapy was used, but not successfully yet is:

The first embryonic stem
cells that were discovered to be totipotent were isolated from a:
