Presentation on theme: "Your “Do Now” 2/28 Get out the assignment from yesterday (Sickle Cell)"— Presentation transcript:
1 Your “Do Now” 2/28 Get out the assignment from yesterday (Sickle Cell) Work on the questions on Part CIf done, review the steps in Part B (what we did)screenshot
2 Your “Do Now” 2/28 ½ sheet of paper (up front) What do you call making mRNA from DNA?What do you call making a protein from mRNA?Genes code for _________ which determine our traitsWhat do you call sets of 3 bases in mRNA?What are set of 3 bases in tRNA that match-up to these?
10 How can recombinant DNA be used? Examples Bacteria making human insulinCuring/treating genetic diseasesBacteria that “eat” oil spills
11 More examples-- 4. Plants that make pesticides 5. Better foods (more “yield”)70-75% of food in supermarket is genetically modified.
12 What do you think about eating genetically modified foods What do you think about eating genetically modified foods? (Putting DNA from one food into another)
13 What do you call an organism that has genes from another organism in it?
14 Transgenic organisms: any organism with another organism’s DNA in it ExamplesMice – used to study human immune systemChickens – more resistant to infectionsGoats, sheep and pigs – produce human proteins in their milkTomatoes —longer lastingCorn –making insecticides
15 Transgenic Goat (not on notes) .This goat contains a human gene that codes for a blood clotting agent. The blood clotting agent can be harvested in the goat’s milk.Human DNA in a Goat Cell
16 How to Create a Transgenic Animal Add the desired DNA to an egg cell
17 CloningMaking an exact copy of an organism using its DNA
26 Your “Do Now” 2/28Get out Notes #4 and be ready to answer these questions:What is genetic engineering?What are 2 ways genetic engineering is used?What are transgenic organisms?What is cloning?
27 Agenda 2/28 Finish Notes #4 Genetic Engineering Online Exploration I will put you in pairs todayShare-out with the class
28 Summarizing Cloning Steps Get a sample of an organism’s DNAInsert it into an egg cellPut the egg in another female
29 We’ve cloned sheep and other animals Can we clone a human?
30 House Bill 2505 Human Cloning Prohibition Act Prohibition on human cloningCriminal Penalty: Up to 10 years imprisonmentCivil penalty: Minimum 1 million dollar fine
31 We cannot clone humans yet… BUT what have we done with human DNA?
32 The Human Genome “Map” of human genes (from DNA) Took 13 years to map all 20,000-25,000 genes in human DNA
33 Gene TherapyCorrecting a genetic disorder by replacing bad DNA with correct gene
34 Solving Crimes Getting a lot of evidence from a little bit of DNA ( PCR) PCR allows scientists to make many copies of a piece of DNA.Heat the DNA so it “unzips”.2. Add the complementary nitrogenous bases.3. Allow DNA to cool so the complementary strands can “zip” together.
35 Gel ElectrophoresisThis technology allows scientists to identify someone’s DNA!Can be used to solve crimesOR prove paternity
36 Proving paternityBabyMan 1Man 2MomCompare the bands from the baby with bands from Mom and Dad
38 Possible dangers of genetic engineering in crops Many varieties of corn are clones of the same plantIf a bacteria or virus infects one plant, it could kill many!
39 Ethical issues with human genetic engineering Should we be allowed to choose our baby’s traits?Should we be allowed to clone a person?
40 Genetic Engineering Reading Exploring the pros and consHIGHLIGHT or UNDERLINE any pros or consADD to notes page
41 BACK OF ARTICLE Quick write You are 18 and going to vote for a candidate. One wants to allow all kinds of GE to be allowed and one is against and GE. Which one would you vote for and why? (back up your claim with examples)
42 GE Online Activity I will put you in partners Follow directions on the sheetPay attention to the times on the sheet!Call us over if you need help
43 GE Online Activity Share-out How can genetic engineering be used in food, medicine, and other areas of life?What makes it controversial?
