Cloning Flashcards
Reproductive cloning
To produce identical cells, tissues and organisms
Molecular cloning
Produce identical genes and useful chemical compounds
Plant cloning can occur through
Vegetative (asexual) propagation
Tissue culture
Vegetative propogation
Growing plants from roots, stems and leaves of a parent plant
Tissue culture
Growing plants from tissues of a parent plant in a growth medium
Four advantages to tissue culture
Production of exact copies- have traits consumers want
Fast growth- quickly produce mature plants
Increased quantity- produce many plants
Virus free stock- fewer losses in H and A
What is a clone
A group of DNA fragments or population of cells, tissues or organisms that are genetically identical
What is cloning
A term given to a biotechnological process that makes identical copies of cells and tissues from pre-existing cells and tissues
How was Dolly the sheep cloned
Dolly was cloned using an egg cell without a nucleus from one sheep and a nucleus from a body cell of another sheep
Two examples of therapeutic cloning
Skin grafting
Bone marrow transplants to treat cancer
The two main groups of stem cell research
Embryonic stem cells
Adult stem cells
Adult stem cells can produce specific cell types like
Skin
Blood
Bone marrow cells
Nerve tissue
