1
Cut off a piece of plant to be used for tissue culture, it is a/an
transplant
explant
implant
apoplant
2
The first steps in cloning mammalian organisms are :
remove egg cell nucleus and add nucleus from desired organism
fertilize an egg cell and supply nutrients
use electrical impulse to trigger egg cell to start dividing
use "domesticated" virus to incorporate desired DNA into egg cell genome
3
Aseptic means :
free from contaminating microbes
sterile
free from bacteria
free from viruses
4
Why are egg cells used in cloning animals?
They contain all of the cell machinery for a new creature
They are larger than most cells
They are easier to work with
They are haploid
5
We can use stem cells to repair/regrow damaged parts of human body that do not naturally regenerate
That can not be done
We already can
Hopefully that could be done
6
Differentiated cells usually have all of the same DNA as undifferentiated
FALSE
TRUE
7
Tissue culture involves : (select all that apply)
nutrient media
intentional contamination
sterile environment
cancer cells
8
Meristems are undifferentiated _______
animal cells
seedlings
plant cells
prokaryotes
9
In plant cell biology, a mass of undifferentiated cells is a/an
petiole
stem
shoot system
callus
10
If your callus can grow roots and shoots with hormone treatment, you get a/an
plantoid
plantar
regenerant
plantlet
11
Differentiated cells : (select all that apply)
can regrow an entire new organism
can not regrow an entire organism
are specialized to be one cell type
can easily form a callus
12
A clone is a group of genetically . . . . . .
heterogeneous plant cells
differentiated stem cells
identical individuals with a common ancestor
identical, but immature egg cells
13
Once a foreign nucleus is introduced to an egg cell, you implant it into a surrogate and hope it develops into an embryo
No, there are other additional steps
Yes, that is basically it.
14
The first mammal to be cloned was a :
frog
sheep
fish
monkey
15
Which of these cell types are undifferentiated?
sperm cells
meristems
stem cells
cancer cells
