![Page 9: Quinoa Mother Grain for Mother Earth. Quinoa and Downy Mildew Quinoa is a highly nutritious and understated pseudo grain Worshiped by the Incas as mother.](https://reader034.fdocuments.net/reader034/viewer/2022051821/5697bfd31a28abf838cac0f4/html5/thumbnails/9.jpg)
Step Three – Designing Gene
Transcription – the synthesis of RNA from a DNA template
Three parts of a genePromoterCoding RegionTermination Sequence
RNA polymerase – enzyme that “reads” the DNA code and builds the mRNA strand
![Page 10: Quinoa Mother Grain for Mother Earth. Quinoa and Downy Mildew Quinoa is a highly nutritious and understated pseudo grain Worshiped by the Incas as mother.](https://reader034.fdocuments.net/reader034/viewer/2022051821/5697bfd31a28abf838cac0f4/html5/thumbnails/10.jpg)
Step Three – Designing Gene (Cont)
Transcription Factor – factors that are needed to produce the mRNA strand or “transcript”
Process:
RNA polymerase binds to DNA strand Double helix unwinds
RNA polymerase moves along the DNA strand (3’ ---> 5’ direction)
![Page 11: Quinoa Mother Grain for Mother Earth. Quinoa and Downy Mildew Quinoa is a highly nutritious and understated pseudo grain Worshiped by the Incas as mother.](https://reader034.fdocuments.net/reader034/viewer/2022051821/5697bfd31a28abf838cac0f4/html5/thumbnails/11.jpg)
Step Three – Designing Gene (Cont)
Ribonucleotides bond to the DNA strand
Result: strand of mRNAStrand of ribonucleotides begins to
break awayDNA strands rewind into double helixRNA polymerase reaches the
termination sequence RNA polymerase and the mRNA strand
released from the DNA strand mRNA strand -----> cytoplasm

Who is our market?
Marketable in countriesJapan- macrobiotic diet (25-30% of
diet cereals and grains). Other Eastern Asian countries such
as India and China “Here in Henan's rural Gushi
County…”Market in Developed Countries—market similarly to wholegrain, with protein and fiber
![Page 34: Quinoa Mother Grain for Mother Earth. Quinoa and Downy Mildew Quinoa is a highly nutritious and understated pseudo grain Worshiped by the Incas as mother.](https://reader034.fdocuments.net/reader034/viewer/2022051821/5697bfd31a28abf838cac0f4/html5/thumbnails/34.jpg)
Problem Addressed and Solution
Fighting malnutrition on a low budget:Economic price: cooked 222 calories for
cup (229g) cooked can be priced around $3 for a .5 kg bag.
Important for a Vegetarian diet—8 + grams of protein per cup
Contains all 9 essential amino acids, 5 grams of fiber (more than prunes, whole wheat, rye)

Problem Addressed and Solution (Cont)
Only issue is water logging, which is easy to revise
Easy to grow- mature seeds germinate once in contact with water
![Page 37: Quinoa Mother Grain for Mother Earth. Quinoa and Downy Mildew Quinoa is a highly nutritious and understated pseudo grain Worshiped by the Incas as mother.](https://reader034.fdocuments.net/reader034/viewer/2022051821/5697bfd31a28abf838cac0f4/html5/thumbnails/37.jpg)
How is it going to be marketed?
Quinoa must be rinsed before packaging—Saponin – natural pesticide
Dried and then packaged in bags or boxes
Versatility of useAs is, Flour, Pasta, many other grain products
Easy storage: cool, dry place, Storage calls for easy transport
