16. Regulation of Expression
Introduction to Regulation of Gene Expression
Multiple Choice
Why is the controlled timing of gene expression crucial to an organism?
A
It ensures that proteins are produced only when needed, conserving energy and resources.
B
It ensures that all genes are expressed simultaneously, maximizing cellular efficiency.
C
It prevents the organism from producing any proteins, maintaining cellular stability.
D
It allows for the random production of proteins, which increases genetic diversity.
Verified step by step guidance1
Understand that gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually a protein.
Recognize that controlled timing of gene expression is crucial because it allows an organism to produce proteins only when they are needed, which conserves energy and resources.
Consider that if all genes were expressed simultaneously, it would not maximize cellular efficiency but rather lead to chaos and waste of resources.
Realize that preventing the production of proteins entirely would not maintain cellular stability, as proteins are essential for various cellular functions.
Acknowledge that random production of proteins does not increase genetic diversity; instead, it could lead to detrimental effects on the organism's health and function.
