Cancer is caused by changes to DNA that control how cells in the body grow and
divide. These genetic changes cause uncontrolled, invasive cancerous cell growth
that spreads into surrounding tissues and then throughout the body. Based on
this information, what can be inferred about the way CRISPR technology could be
used to treat cancer? - ✅✅by editing the damaged DNA in cancerous cells -
Researchers hope that CRSPR technology can be used to genetically modify
cancer cells, cutting or replacing the damaged DNA that is responsible for the
abnormal growth.
Compare the traditional technique of selectively breeding plants or animals to
modern genetic engineering and how it can transform crops, fish, or livestock
today. If this type of biotechnology was used to domesticate corn (rather than
selective breeding), what would have been the MOST likely result? - ✅✅the
process would have been much faster - With selective breeding, culling organisms
with undesirable traits and breeding only those with desirable traits is a slow and
laborious process, with potentially mixed results. Genetic engineering allows for
specific traits to be targeted and reproduced in a single generation, so corn could
have been derived from teosinte much more quickly.
Omega-3 fish oil is a popular health supplement. Manufacturers used to obtain
omega-3 from algae-eating fish, but industrial biotechnology now enables them
to extract it directly from algae instead. What is the MOST direct benefit from this
advancement in fish oil production? - ✅✅it conserves resources - Obtaining
omega-3 from algae instead of fish conserves wild fish as well as all the resources
that would otherwise have been used to farm fish for their oils. For example,
aquaculture threatens the health of aquatic ecosystems and requires vast
amounts of antibiotics, hormones, and pesticides to keep the penned-up fish
healthy.
, agritech - ✅✅alternative term for agricultural biotech
biodefense - ✅✅drugs used to counter bioterrorism attacks
biofuels - ✅✅fuel produced from biological products including agricultural
products, animal waste, and forest materials
bioterrorism - ✅✅terrorism involving the release of toxic biological agents
CAR-T - ✅✅chimeric antigen receptor t-cells uses the body's t-cells to harness
the immune system to fight cancer
CRISPR - ✅✅a genetic engineering tool
gene therapy - ✅✅transplantation of normal genes in cells in place of missing
or defective ones in order to correct disorders
immunotherapy - ✅✅the prevention or treatment of a disease/disorder using
technologies or substances that stimulate an immune response
industrial enzymes - ✅✅enzymes used in the production of processing of
products from biomass and in biomaterials
MedLinePlus - ✅✅a web-based library information service of the US Library of
medicine
