Genetic engineering assignment.... please help!
1) choose an organism that you would want to genetically engineer (obviously not dinasour)

2) explain how you would genetically engineer this organism.

3) explain the pros and cons of having your genetically engineered organism roaming the environment.

4) Because individuals survive, mate and reproduce rather than individual traits, we expect that many traits in an organism will be phenotypically and genetically correlated. List two of the possible evolutionary outcomes that can occur when selection operates on genetically correlated traits (1), and explain why these outcomes occur (3). Give an actual, not hypothetical, example for one of them using a real organism (1).

Please help!

Q1.

You are a genetic engineering hired by the biotechnology company, Genes 'R' Us, to use genetic engineering to develop a new rose that glows. Place the following steps in the order you would need to perform them to successfully genetically engineer the rose with this trait.

-Extract all of the DNA from a firefly cell

-Use traditional plant breeding techniques to improve the performance of the rose, which has the new glowing gene (transgene)

-Clone the single gene that encodes the glowing protein

-Insert the glowing gene into single rose plant cell using either the gene gun or agrobacterium

-Modify the glowing gene so it acts In the way you want it once its inside the rose plants

-Identify the firefly as an organism that would have a gene encoding a protein for a âglowing traitâ

Q2.

Genetic engineering is different from traditional plant breeding in that (select all that apply)

___genetic engineering 'physically' removes DNA (genes) from one organism and inserts them into another

___plant breeding and classical biotechnology relies on natural sexual reproduction to create variation while genetic engineering introduces variation one or a few genes at a time into a single cell.

___genetic variation used in classical biotechnology (plant breeding) comes from mutations in genes already found in that crop species. In genetic engineering, new genes are added to the genetic makeup of a plant

___genetic engineers can move DNA from any organism into any organism, even if they are not in the same species.

Q3.

Which method of plant transformation works and depends upon an organism that is a "naturally occurring" genetic engineer?

A)Gene Gun

B)Agrobacterium

C)Microneedle insertion into a plant egg cell

D)Electric Shock of Plant Cells

Once a genetic disorder in an adult is treated successfully through gene therapy, it is highly unlikely that the person's children will inherit the gene(s) for the disease.Answer TrueFalse Vaccines produced by genetically engineered bacteria contain the antigen(s) of the disease-causing organism, not the organism itself. Answer TrueFalse .1 points Question 11 Restriction enzymes are used in genetic engineering to cut DNA between specific base pairs in a DNA strand, resulting in DNA segments that are then used for further study and analysis. Answer TrueFalse .1 points Question 12 Plasmids are useful to scientists involved in recombinant DNA technology because foreign genes can be inserted into the plasmids and then the plasmids can be inserted back into bacteria. Answer TrueFalse
