This document provides an overview of genetic engineering and biotechnology concepts through a series of slides. It discusses how DNA from different organisms can be spliced together, and how genetic engineering involves manipulating genes. Examples are given of inserting select genes into organisms to improve traits or have them mass produce certain proteins. The document also summarizes gene cloning techniques like PCR and discusses applications of genetic engineering in medicine, agriculture, and animal science. Ethical considerations around topics like patenting life forms and conducting safety research are also briefly outlined.
A physical map of a chromosome or a genome that shows the physical locations of genes and other DNA sequences of interest. Physical maps are used to help scientists identify and isolate genes by positional cloning.

The Documented Health Risks of Genetically Engineered Foods (Long Version)Jack Olmsted
Content of the Presentation
Regulatory Failure: It is useful to explain how such dangerous products could have made it to the market with government approval. Several slides include quotes from formerly secret FDA documents that show how government policy was at odds with more cautious scientific opinion at the agency.
Health Risks of GMOs: This section highlights many of the adverse findings revealed through laboratory experiments and reported by farmers, doctors, and investigators. It also introduces some theoretical risks based on the current state of the science.
The Consumer Tipping Point: The final section includes a discussion of a strategy to achieve the tipping point of consumer rejection of GMOs in the US, which is the basis for our Campaign for Healthier Eating in America. The key elements needed are consumer education on GMO health risks combined with clear non-GMO choices.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. • All living things use the same 4 nucleotide
bases of DNA (A-T, C-G) & ribosomes
• THEREFORE, DNA from different organisms can
be joined or ‘spliced’ together… GENETIC
ENGINEERING
3
4. G E N E T I C E N G I N E E R I N G
• Recombinant DNA technology
• Gene manipulation
1. genes are engineered by scientists into
organisms such as microbes or bacteria, for
mass-production
2. insertion of select genes into organisms to
improve their genotype
4
6. Recombinant DNA
Combine DNA from different sources
Identify a particular gene
Cut out the gene with restriction enzymes
Insert the gene into the DNA of another
organism
Example: creating E.coli bacteria that produces
human insulin
Transgenic organisms– inserting DNA
from one species from one species into
another (of another species)
8. GENE CLONING
1. Isolate a gene
2. Make copies – using PCR
(polymerase chain reaction)
3. Insert the gene into a plasmid
from a prokaryote
(eukaryotes are too hard
to work with)
4. Study the gene & look for
translation: If the new gene
is expressed in the cells of
the targeted organism; success
12. MEDICINE: 1970’s we learned to put genes into
bacteria that would make human insulin; Insulin
separated from bacteria & given to diabetics
Desired human gene
(like insulin production)
12
13. CRISPR: New technology
(Clustered Regularly Interspaced Short
Palindromic Repeats)
• efficient and reliable way to make precise,
targeted changes to the genome of living cells

GMO’s & FOOD
Two major categories of GMO crops:
1. Crops to resist pests= turning plant into its
own pesticide
2. Crops resistant to herbicide, Roundup=
farmers spray crops with Roundup & all
plants/weeds are killed except the crop
VIDEO: What is a GMO? (3 min)
17. G M C R O P S
Biofortified Rice “Golden Rice”
• Vitamin A deficiency causes 500,000 cases of
blindness and up to 2 million deaths each year
• in countries where rice is the staple diet
• Golden Rice was engineered so that the rice
plant produced Vitamin A

20. European Corn Borer
Corn Borer- insect that kills
corn crops
U.S. + Canada: > $1 billion per
year, damage + control costs
Bt Corn
20
21. Bt – Bacillus thuringiensis – common soil borne
bacterium- produces crystals that kill insects when
eaten.
• Scientists insert Bt
genes into corn
genome
• Corn plant produces
Bt in every cell
KnockOut (Novartis)
YieldGard (Monsanto)

Way in GM Crops
VIDEO: How are GMO’s created?
(5:30) 22
23. How are GMO’s tested & approved?
EPA- (Environmental Protection Agency) evaluates
environmental safety
USDA- (US Department of Agriculture) evaluates
whether plant is safe to grow
FDA- (Food & Drug Administration) evaluates
whether the plant is safe to eat
23
24. How are GMO’s tested & approved?
1. Scientists have to perform studies on the new
product & determine it safe
2. Scientists present the data to the EPA, USDA,
FDA
3. EPA, USDA, FDA approves product

QUESTIONS: Who are the scientists?
Is their data transparent to the public?
TRUTH:
26. What’s the Debate?
VIDEO: “What’s the Deal with Genetically Modified Food? (3min)
AgBioTech
Aventis (Hoechst + Rhone Poulenc)
Monsanto (Monsanto + Pharmacia+ Upjohn)
Dupont (Dupont + Pioneer Hybrid)
Syngenta (Novartis + AstraZeneca)
Bayer
Dow Chemical (Dow + Elanco)
5 Firms – each Multinational:
68% of agrochemical market
worldwide
20% of commercial seed worldwide
26
ANSWERS: The
scientists supplying
the safety data are
hired by these
companies.
The data is NOT
transparent to the
public.
TRUTH:
27. LAWS:
• Current laws allow industries to patent/own
the intellectual property that they genetically
modify/create
• Ownership of the new genome/organism
• Allows companies to charge whatever fee they
wish for use of their patent, including further
research in the area
ETHICAL ISSUES:
• sitting on technology or creating monopolies
• Is it OK to patent/own life forms?
28. GM Pesticide resistant crops:
genetically alter plant to contain a pesticide toxin that will
prevent pests
(+) More crops & less
damage
(+) More money for NC
business & economy
(+) No current health
concern (passed by the
FDA)
(+) No current
environmental concern
(passed by the EPA)
(-) possible creation of
pesticide resistant insects &
pathogens
(-) uncertain long-term effects
of natural ecosystems
(-) uncertain long-term effects
on human body
(-) kills other beneficial insects
including Monarch butterfly
(-) labelling?
(-) who’s doing the research?

29. GM Crops- Other Issues
• Threat to small farmers
• Some say that GM technology benefits big
business not the poor
• Cross-pollination of GM crops with organic
farms
• Patenting life forms
• Bio-piracy
• Terminator technology
• Politics: Frankenfoods

30. A N I M A L S :
Scientists engineer
featherless chicken by
removing feather gene
Scientists engineer
‘glowing’ mice from
bioluminescent gene in
a jellyfish

31. Cloning: produces an organism that is an exact
genetic copy of another
EXAMPLE: Dolly the sheep July 1996
• Scientists took nucleus from adult sheep &
implanted that into sheep egg cell
• Then placed modified cell into female sheep
and when offspring was born, it had identical
DNA of adult sheep
31
32. SOMATIC CELL TRANSFER
making an identical organism
use a somatic cell and enucleated egg cell
1. Egg is removed from Egg Cell Donor
• Nucleus is taken out and discarded
2. Somatic cell is taken out of a Somatic Cell Donor
• Nucleus is taken out and put in the egg cell
3. Egg and nucleus is zapped to start dividing
4. Placed into a Surrogate mother and results in a
healthy baby (hopefully)
35. Stem Cells: cells that are part of the embryo
during early development- before they become
specific body cells
(embryonic & adult stem cells)
• These cells are useful in science because they
can be used to perform desired medical
functions- we can direct them
VIDEO: What are
stem cells? TED Ed
(4 min) 35
36. Genetic engineering & you:
(+) medical knowledge
in your DNA could help
prevent diseases
(+) personal medicine
for your DNA
(+) organ transplants
from your own cells
(+) birth defects can be
avoided
(-) when is it going too far?
(-) who has access to your
DNA information?
(-) whose cells will you use?
(-) how is research
conducted? Who are the
test subjects?
36
37. Genetic Engineering Other Issues
• What is going too far?
• STEM cells- when is a human ‘alive?’
• What if insurance companies could know
about your DNA?
• Should DNA information be kept in databases
or is it your personal information? Who will
regulate this?

Study all DNA notes
• DNA structure & function
• DNA replication
• Protein synthesis (from DNA to RNA to protein)
• Mutations
• DNA technology
