Biotech Flashcards
recombinant DNA
fragments of dna can be joined together with the help of special enzymes, creating an artificial assembly of genetic material
dna cloning
the introduction of recombinant dan into a host cell, followed by the copying and propagation of the introduced dna in the cells of the host and all of its offspring
biotech
the altering of DNA,cells,organisms
dna sequencing
consistency in the chemical structure of dan means that similar lab techniques can be used to isolate and analyze dna from diff species (bacteria, woolly mammoth)
why use biotech or genetic engineering?
- to learn more about cellular processes 2.to better understand and develop treatments of disease 3.for economic and commercial benefits a.to get transgenic organisms that express recombinant dna b.dna tech is used in forensics and to help diagnose genetic disorders and infectious disease
gene therapy
being tested as treatment of serious genetic disorders caused by the malfunction of a single gene
genetically modified organism (GMOs)
organisms that have been genetically engineered
dna fingerprinting
the process of identifying dna unique to a species or individual and is especially important in forensic science. scientists examine certain regions of the human genome that are known to vary greatly from 1 person to the next
-used in public health
how is dna fingerprinting done?
- collect samples
- cut dna with restriction enzymes
- run dna through gel
what other uses can fingeprinting be used for?
- match organ donors
- paternity testing
- identify victims of mass attacks
dna fingerprinting can be used to detect the contamination of food or water by certain harmful microorganisms? true/false
true
dna tech can be used by consumers to trace ancestry and it has revealed our relationships with extinct humans? true/ false
true
how has genetic engineering focused to improve medicine
- replacement of defective genes (gene therapy)
- production of protiens (drugs)used to treat illness
- creation of new vaccines
