Flashcards in Chapter 1.6 Genetic Engineering Deck (14):
Normal control of bacterial cell activity depends on
Genetic information can be transferred from the cells of one species to the cells of another either
naturally or artificially
Natural methods of transfer include
fertilization in animals and plants and the transfer of plasmids between bacterial species or by viruses.
Artificial transfer of genetic information is called
Genetic engineering often but not always involves
Pieces of chromosome can be transferred from a
donor species to another which then allows the recipient species to make new proteins.
Genetic engineering is carried out by humans to allow a species to
make a protein that is normally made by another species.
Stage 1 of genetic engineering is:
Identifying a section of DNA that contains the required gene from the chromosomes of a donor species.
Stage 2 of genetic engineering is:
Extracting the required gene
Stage 3 of genetic engineering is:
Inserting the required gene into a vector or bacterial plasmid
Stage 4 of genetic engineering is:
Transforming the recipient (host) cell by placing the modified plasmid into it.
Following a genetic engineering, transformed cells are cultured to produce a
GM (genetically modified) strain or organism
The GM strain or organism can produce
a new protein normally made by another species
