Textbook Question

Chapter 10, Problem 1SA

Gene expression does not vary by ________.

a. cell type	c. stage of development
b. extracellular conditions	d. the genetic code

Expert Solution & Answer

Summary Introduction

Introduction:

Gene expression refers to the process in which the information present in the genes is used to obtain functional gene products in the form of proteins. The response of a cell varies with rate of gene expression.

Answer to Problem 1SA

Correct answer:

The genetic code does not alter the gene expression. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

Option d. is given as “the genetic code.”

The genetic code codes for an amino acid. Many amino acids make peptide bonds with each other to form a polypeptide. The change in genetic codes alters the protein expression, not the gene expression.

Reason for incorrect answer:

Option a. is given as, “cell type.”

The expression of gene changes in different types of cells or tissues. The genes are highly expressed in bone marrow, parathyroid gland, and in some regions of the brain. The lower level of gene expression can be found in regions like ovary and salivary gland. So, the cell type changes the gene expression. Hence, option a. is incorrect.

Option b. is given as “extracellular conditions.”

Extracellular condition like lack of nutrients, signals from the extracellular matrix affects the gene expression. The availability of the preferred nutrient in the surrounding starts transcribing genes in organisms, so its product allows the cell to utilize the nutrient. The unavailability of the nutrient stops the transcription of the genes. So, extracellular conditions can alter gene expression. Hence, option b. is incorrect.

Option c. is given as, “stage of development.”

During embryonic development, a cell differentiates to form tissues, organs, organ system, and then it finally forms an organism. This complete developmental process is regulated by a cascade of master gene expression. The product of these genes affects the expression of other genes. Therefore, developmental stages affect the expression of genes. Hence, option c. is incorrect.

Hence, the options a., b., and c. are incorrect.

Conclusion

Therefore, gene expression does not vary by the genetic code. Thus, the correct option is d.
