Answer 1

1.  c. all of the above are true of embryonic stem cells

2. c. Plants that were bred to have a red flower(flowers are naturally red or white). Is not a transgenic organism. This is developed through breeding technique.

3. a. Protein, In recombinant DNA, DNA undergoes transcription followed by translation gave concerned protein encoded by r-DNA.

4. Embryonic stem cell:

a. Are called hematopoietic stem cells, They have pluripotent in nature (They can develop into the most type of cells not all) and they can divide indefinitely.

5. Ans: a

Gene therapy involves giving a patient __Genes___ to produce protein that the patient makes abnormally:

Gene therapy is the introduction of a normal gene into an individual’s genome in order to repair a mutation that causes a genetic disease.

6. Therapeutic cloning involves giving a patient _____to repair damaged tissue:

a. Cells (Stem cells are used to treat the patient is called Therapeutic cloning)

7. Which of the following are uses of recombinant DNA? Ans: e all the above.

a. Produce proteins to be used as drugs

b. Production of transgenic animals

c. cloning a gene

d. Giving plants new physical characteristics

e. All above

8. Transgenic crops:

Benefits: 1. Can introduce a beneficial character directly into undifferentiated cells and develop the new character. This achieved in short time, unlike breeding.

2. Develop the biotic/abiotic resistance crop and can improve the agnomical traits.

Problem:

1. Development of transgenic means introducing foreign gene into plant. This is type mutation. This made an evolutionary change.

2. Horizontal gene flow.

9. GMOs

1. Flavr Savr tomato

a) Delayed the ripening of tomato.

b) It possible for long-term storage

2. Bt cotton

1) Produce the crystal poteins

2) Develop the resistance for yellow stem borer, more yield.
