Definition
-creation of organism that is an exact copy another
-identical DNA |
|
|
Term
|
Definition
| splitting an embryo to produce two new embyros that are implanted and become genetically identical organisms |
|
|
Term
|
Definition
| cellular compartment where genetic information is stored |
|
|
Term
|
Definition
| all cells in organsim except sperm and egg |
|
|
Term
|
Definition
using nucleus from a somatic cell to produce an organism identical to somatic cell donor
-clones will be slightly different |
|
|
Term
| embryo splitting (twinning) |
|
Definition
-cells come from same zygote
-occurs in petri dish instead of mothers body
-manually seperating early embryo into individual cells
-can't clone adults |
|
|
Term
| somatic cell nuclear transfer (SCNT) |
|
Definition
isolate somatic cell from female sheep, transfer nucleaus from cell to egg cell which nuclease has been removed, egg cell behaves just like freshly fertilized zygote
-can clone adults |
|
|
Term
|
Definition
1. remove nuclei from egg cel
2. inject somatic nucleus into enucleated egg cell
3. allow reprogramming of the cell
4. allow the development of an embryo to begin
5. implant into a surrogate mother
6. deliver the clone |
|
|
Term
----donate DNA to baby sheep
baby sheep is clone of ---- sheep |
|
Definition
-both sheep
-cell that is given and put into egg |
|
|
Term
|
Definition
| uses same steps as reproductive up until blastocysts, destroy this, and take cells to make into stem cells |
|
|
Term
|
Definition
| -use blastocysts, put into surrogate mother to make a new individual |
|
|
Term
|
Definition
-resets gene expression
-genes may develop differently because of enviorment or mitochondrial DNA |
