Textbook Question
Chapter 10, Problem 19P
The figure below shows DNA fingerprint analysis of the genomic DNA from semen associated with a rape (***) and from mouth swabs (somatic cells) of individuals 1–4. This analysis involves the PCR amplification of six SSR loci, each from a different (nonhomologous) chromosome. All PCR primers used are 20
| a. | Sperm are haploid, but the semen sample shows two different-sized PCR products for certain loci. How is this possible? |
| b. | Is any locus on the X chromosome? If so, identify it. |
| c. | Is any locus on the Y chromosome? If so, which one? |
| d. | Explain why these results demonstrate that none of the four individuals is the rapist. What pattern would you expect by analyzing mouth swab DNA from the rapist? |
| e. | Do these results nonetheless provide any information that could help catch the rapist? If so, be as specific as possible. |
| f. | The two orange bands amplified by PCR from the semen are 200 and 212 bp long. How many tandem repeats of the SSR repeat unit are found in the two alleles of this locus in the rapist’s genomic DNA? (Assume that the PCR products are the shortest possible and that the repeat unit for this locus is TCCG.) |

In a natural population of outbreeding plants, the variance of the total number
of seeds per plant is 16. From the natural population, 20 plants are taken into
the laboratory and developed into separate true-breeding lines by self-
fertilization-with selection for high, low, or medium number of seeds-for 10
generations. The average variance in the tenth generation in each of the 20 sets
is about equal and averages 5.8 across all the sets. Estimate the broad-sense
heritability for seed number in this population. (4 pts)

- Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration. Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpoarrow_forward3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L.
