dna technology Flashcards
cloning is
producing many copies of an organism
Gene cloning is
producing many copies of one gene
recombinant dna is…
adding forgein DNA into an organism using vector or carriers
how is gene cloning done (2 ways)
recombinant dna & polymerase chain reaction
process of making recombinant DNA
1 restriction enymes cut open vector
2 restriction enzymes cut opn dna of interest
3. the ticky ends meet
4. foreign vector and dna complimentary base pair
5 ligase seals them together
uses of recombinant DNA
Cloning genes, producing proteins (insulin), transgenic organisms, gene therapy
why do genetic mutations happen
a change in organism due to a chemical change in the structure of a gene
mutagen
something that causes a mutation
examples of mutagen
UV light, toxins, asbestos, cigarette smoke, x-rays
chromosome mutation
pieces or whole chromosomes are lost, added, or moves- responsable for most birth defects
gene mutations
one or more base pair of a DNA molecules are altered
