Textbook Question
Chapter 7, Problem 2CT
In a variation of the experiment in the previous question, the following materials were added to three separate cell-free systems, generating the indicated results:
| Materials Added | Results |
| Radioactive amino acids | Radioactive protein produced |
| Radioactive amino acids and DNase (a DNA-digesting enzyme) | Radioactive protein produced |
| Several hours after grinding: Radioactive amino acids and DNase | No radioactive protein produced |
What is the best interpretation of these observations?

In the experiment by Bernard Davis, bacterial F+cells and F- cells were growing while separated by a filter. Filter pores allowed the passage of the liquid medium but not the bacteria cells. As a result:
1) prototype colonies grew well on minimal medium
2) F+ cells were converted to F- cells despite the physical separation
3)F- cells were converted F+ cells despite the physical separation
4)F+ cells were not converted to F- cells because of the physical separation
5) F- cells were not converted to F+ cells because of the physical separation
6)there was no growth of prototypes on minimal medium
When preparing cells for karyotyping, in which of the following solutions should the cells be immersed?
A.-Isotonic
B.-Hypertonic
C.-Melted Sugar
D.-Hypotonic
E.- Saline at human body temperature
What is denaturation and why is the process harmful to a cell?

- A lab trainer instructed a new lab recruit to freeze down cells from a tissue culture flask to save for future use. After verifying that the flask of adherent cells was confluent, and contained enough cells to freeze down, the lab trainer left the recruit to go through the freezedown protocol. A few days later, the trainer thawed out the cryovials of cells that the recruit put away, and discovered that there were very few viable cells. Assuming that the lab trainer did everything correctly, answer the following: What are two possible mistakes made that explains why there are so few cells? Explain why those mistakes had the effect they did.arrow_forwardA panel of cell lines was created by human–mouse somatic-cell hybridization. Each line was examined for the presence of human chromosomes and for the production of an enzyme.
