1. Choose the correct statement. (Points : 3)
A.Your lungs look different from your heart because the cells that make up these organs have different genes.
B.All cells have the same genes, but different genes are active in different cells.
C.As cells and tissues differentiate, they lose some of their genes.
D. All cells have the same genes, and all of a cell's genes are active at the same time.
3. What must happen for transcription of the lac operon genes to take place? (Points : 3)
A.The repressor protein binds to the DNA molecule, and RNA polymerase falls off.
B.Lactose is removed from the system.
C.The repressor protein binds to the promoter sequence.
D.The repressor protein falls off the DNA molecule, and RNA polymerase binds to the promoter.
4. What could lead you to conclude that the lac operon is on? (Points : 3)
A. RNA polymerase is blocked by the repressor.
B. Lactose is absent.
C. The cell membrane changes.
D.The repressor protein has fallen off the molecule.
5. How is the cell in Diagram B effectively using its resources?(Points : 3)
A.RNA polymerase is transcribing the genes since lactose is present.
BSince lactose is present, the repressor protein will begin transcription.
CSince lactose is absent, the repressor protein is blocking the genes and stopping transcription.
DThe cell continually produces the enzymes needed to break down lactose.
6. If scientists were trying to construct recombinant DNA molecules, how would they do it? (Points : 3)
A.by using RNA from plants
B.by combining the RNA of two different organisms
C.by combining the DNA of two different organisms
D.by combining the proteins from two different organisms
7. Scientists involved in biotechnology sometimes insert the DNA of one organism into a second organism. What is the purpose of this process? (Points : 3)
A.to reverse the organisms' gene expression
B.to cause the second organism to produce proteins
C.to create different traits in the same species
D.to make ATP
8. How is the information in a DNA molecule expressed in an organism? (Points : 3)
A. through recombinant DNA
B. through proteins
C. through plasmids
D. through RNA polymerase
9. Cells in your hair follicles produce the protein keratin, which is a primary component of hair. Cells in your liver do not produce keratin. What is the reason this specialization occurs? (Points : 3)
A. Different types of genes are activated in liver cells and hair follicle cells.
B. Hair follicle cells contain different genes from liver cells.
C. Hair follicle cells do not produce DNA, but liver cells do.
D. Hair follicle cells contain recombinant DNA.
10. When a human embryo is developing, the embryo produces a special type of hemoglobin not found in infant, child, or adult blood. Which of the following best explains how an embryo can produce a different type of hemoglobin than an infant, child, or adult? (Points : 3)
A. The embryo has different genes than the infant, child, or adult.
B.Humans have genes for the different types of hemoglobin, which are expressed at different times.
C. Development and differentiation result in the loss of certain genes.
11. The term gene expression can be best explained by which of the following? (Points : 3)
A. an increase in the amount ofRNA polymerase
B. the production of proteins based on the genetic information in DNA
C. the production of nucleic acids
D. the suppression of DNA replication
12. Which molecules in eukaryotic cells regulate gene expression? (Points : 3)
A. recombinant RNA
B. replication factors
C. oxygen
D. transcription factors
13. What would happen if a chemical interfered with the ability of RNA polymerase to bind to a DNA molecule? (Points : 3)
A .The DNA molecule would replicate itself.
B. Transcription would proceed, and a protein would be produced.
C .The RNA polymerase would cut the DNA molecule in half.
D. Transcription would not take place, and the protein would not be produced.
Answers:
1 B.All cells have the same genes, but different genes are active in different cells. Recall in movie "Jurassic Park" they closed a complete dinosauar with drop of blood found in amber encased misquito. Ddi not need dameple of brain cells or lung cells
7 B. to cause the second organism to produce proteins
ho great if a cow could make human insulin
13 RNA copies pattern for protein from DNS,interefer and there is no patten thenno protein

I know is sounds unkind but I tend to side with your mum on this.Do you really want to tie yourself down with someone with the issues this guy has.Apart from anything else with diabetes he certainly should not be smoking.I have diabetes in my family and it is a very dangerous condition which, if you do not look after yourself, will kill you.However, if you DO take care of yourself you can live with it quite well.
If you want to have children then you owe it to them to give them a happy secure future, and I am talking financially here.Money doesn't buy happiness, but believe me life can be very very miserable if you don't have it and it limits your life choices.One other thing,any children you had with this guy stands a very high risk of also getting diabetes.You don't give your age but I imagine you are quite young.You and any children you have in the future deserve the best out of life you can get.This guy obviously won't be able to provide for you and your children – go find someone who can.
The one comment you made was you don't want to leave him over things he has no control over, and I totally agree. Dating someone and they find out they have cancer, or they are in a car accident and loose a leg, these are things they can't control. However your boyfriends diabetes and hair loss, and passing out all have to do with how he eats, so I would sit him down and explain to him what he means to me., How much I love and care about him and for that reason I am not going to be able to sit by and watch him slwoly kill himself, he needs to go and see a diatician who can give him some good food choices, etc and get to talking to a gym insturctor etc. He needs to put plans in action to live a healthy lifestyle because you want him around, for a long time, or you do not see the point of continuing.
yeah i woulldnt he just wants a nursy mommy unless you love him so much you can support him then go ahead but skitso mom is right
If his health issues concern you then you should make sure he's willing to do the things it takes to manage them. Otherwise you're setting yourself up for heartbreak. But aside from that there is NO REASON to end a relationship with someone because they have diabetes. I'm shocked that you're even considering it.
You're not going to "risk your mom's mental health by going against her desires". WTF do you even mean by that?? Is she going to control your life forever?
