Question

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.

Expert Solution & Answer

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.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
