To examine: Whether the statement “Because the DNA double helix is only 2 nm wide-well below the limit of resolution of the light microscope-it is impossible to see chromosomes in living cells without special stains” is true or false. Introduction: The light microscope is a type of instrument that uses the visible light to observe the images of small objects. The limit of resolution of the light microscope is set by the wavelength of visible light that ranges from 0.4 μm to 0.7 μm.

Summary Introduction

To examine: Whether the statement “Because the DNA double helix is only 2 nm wide-well below the limit of resolution of the light microscope-it is impossible to see chromosomes in living cells without special stains” is true or false.

Introduction: The light microscope is a type of instrument that uses the visible light to observe the images of small objects. The limit of resolution of the light microscope is set by the wavelength of visible light that ranges from 0.4 μm to 0.7 μm.

Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is true.

Explanation of Solution

The objects that are 500nm wide are able to detect clearly under the light microscope. However, smaller than this size appears blur due to wave-like nature of light. The DNA double helix is only 2 nm wide. Thus, it is below the limit of resolution of the light microscope. Hence, it is not possible to see the chromosomes in living cells under the light microscope without special stain. Hence, the statement is true.

a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involved

If you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F. Interval; Do not change the interval
