SPECIATION MNEMONIC
CLASSIFICATION MNEMONIC
GENETIC MODIFICATION 1
Cut out the gene that codes for desired characteristics from the chromosome of an organism
Insert gene into the chromosome of an organism at an early stage of development
GENETIC MODIFICATION
1) remove DNA plasmid from the bacteria
2) cut open the plasmid using an enzyme
3) healthy insulin gene from the chromosome of a human
4) join gene into plasmid using an enzyme
5) put plasmid back into bacteria
6) grow bacteria and make the substance you want
SELECTIVE BREEDING
CLONING : PLANT CUTTINGS
Take cuttings from parent plant and plant them to make clones with the same gens
CLONING: PLANTS TISSUE CULTURE
Scrape off a few plant cells and grow them into new plants in special nutrients
ANIMAL CLONING : Embryo transplant
1) Take egg and sperm from prize cow and bull and artificially fertilise
2)leave to develop into an embryo and split embryo many times before any cells become specialised
3) transplant embryos into the wombs of other cows
4)the embryos are clones so all calves will have the same genes
ANIMAL CLONING : ADULT CELL
1) remove the nucleus of an egg cell
2) Remove nucleus from an adult body cell and put into empty egg cell
3) electrically stimulate the egg cell to divide into an embryo
4)put embryo in female uterus
5) it will grow into a clone of the original organism
