Crossing similar individuals to bring together the best of both organisms. Application of technology process, invention, or method to living organism. Joining together dna from two or more sources. A gene that makes it possible to distinguish bacteria that carry the plasmids from those that don"t. Member of a population of genetically identical cells. Process of changing a gene to treat a medical disease or disorder. Technology to study hundreds or thousands of genes. Analyzing section of dna that may have little or no function. Scientific study of interaction with which an organisms might interact. Living parts of the environment with which an organism might interact. Uses solar or chemical energy to produce food. The first producers of energy rich compounds that are later used by other organisms. Captures light energy and uses its power chemical reactions. Organisms that relay on other organisms for energy. A group of similar organisms that can breed and produce fertile offspring.

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

Assume that you are trying to insert a gene into a plasmid andsomeone gives you a DNA sample cut with restriction enzyme X. Thegene you wish to insert from the given sample has sites on bothends for cutting by restriction enzyme Y. You have a plasmid with asingle site for Y, but not for X. Your strategy should be to

cut the plasmid with restriction enzyme X and insert thefragments cut with Y into the plasmid.

cut the plasmid with enzyme X and then insert the gene into theplasmid.

cut the DNA again with restriction enzyme Y and insert thesefragments into the plasmid cut with the same enzyme.

cut the plasmid twice with restriction enzyme Y and ligate thetwo fragments onto the ends of the human DNA fragments cut withrestriction enzyme X.

insert the fragments cut with X directly into the plasmidwithout cutting the plasmid.
