Chapter 8, Problem 1MCQ
Summary Introduction

Introduction:

Almost all the cells in an organism are genetically identical, but different types of cells look different which results from differential gene expression. Genes are expressed by turning on and turning off its expression as a result of interaction with regulatory proteins.

Answer to Problem 1MCQ

Correct answer:

A pancreas cell has a different function and structure from a brain cell, but the cells have identical DNA. Therefore, option d is correct.

Explanation of Solution

Reason for the correct statement:

Differential gene expression is responsible for the specialization of different cells with the same genome to perform different functions within an organism. Hence, all the cells in a body contain similar DNA.

Hence, option d is correct.

Reasons for incorrect statements:

Option (a) is given as “because the cells contain different genes”.

The entire cells in a body contain similar genetic content. Hence, it is a wrong answer.

Option (b) is given as “because the cells contain different chromosomes”.

The entire cells in a body contain similar chromosomes. Hence, it is a wrong answer.

Option (c) is given as “because the cells have different replication proteins”.

All the eukaryotic cells contain same replication protein. Hence, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

The entire cells in a body contain similar DNA. Differentiation is the process by which cells become different in structure and function.

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.
Case Study—Ella Review the case study and then answer Parts A through F. Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day.
