Concept explainers
Hemochromatosis is an inherited disease caused by a recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of each of the following?
(a) All three children are of normal
(b) One or more of the three children have the disease.
(c) All three children have the disease.
(d) At least one child is phenotypically normal.
(Note: 1t will help to remember that the probabilities of all possible outcomes always add up to 1.)

- 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 intervalarrow_forwardWhat percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent.

- There are a wide range of therapeutic applications available as options for patients. Medical professionals should be aware of these applications so they can make informed recommendations to patients. To gain a better understanding of some therapeutic applications and how they are related to RNA and mRNA, research long non-coding RNA. Respond to the following in a minimum of 175 words: What is lncRNA and what does it do? How does IncRNA differ from mRNA? What are some therapeutic applications associated with lncRNA?
