Chromosome is a thread like structure composed of nucleic acid and protein present in living cells that carry genetic information in the form of genes. It is found in both plants and animals. In humans total 46 pair of chromosomes are present that occur in 23 pair. 22 pairs are similar in both male and female is called autosome while 23 pair is called sex chromosome which is different in male and female. In females, XX chromosomes is present while in males XY chromosome is present

Expert Solution & Answer

Answer to Problem 1A

Correct answer: Two sister chromatids are attached by centromere. Therefore, option (c) is correct.

Explanation of Solution

Reason for the correct statement:

Centromere is the region of chromosome on to which sister chromatids are attached to centromere. During mitotic division the centromere splits and sister chromatids give rise to daughter chromosome.

Option (c) is given as “centromere”.

As “the point of attachment for two sister chromatids is the centromere”, it is the right answer.

Hence, option (c) is correct.

Reasons for the incorrect statements:

Option (a) is given as “centriole”.
Centriole is a cell organelle made up of tubulin protein and protein strands called microtubules. It is only found in animal cells. It helps in division of cells. So, it is a wrong answer.

Option (b) is given as “chromosome”.
Chromosome is a thread like structure composed of nucleic acid and protein present in living cells that carry genetic information in the form of genes. It is found in both plants and animals. So, it is a wrong answer.

Option (d) is given as “karyotype”
It is a type of test used to identify the shape, size and number of chromosome in an individual. . So, it is a wrong answer.

Option (e) is given as “chromatin”.
Chromatin is complex formed by DNA, RNA and specialized protein called histones. Nucleosome is the unit of chromatin. So, it is a wrong answer.

Hence, options (a), (b), (d) and (e) are incorrect.

Conclusion

The two sister chromatids are attached by the centromere.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just 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: (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 po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present.
