What is one difference between gene regulation in prokaryotes and eukaryotes? (1 point)
A. • Eukaryotes transcribe genes in response to environmental stimuli while prokaryotes transcribe genes randomly.
B. • All eukaryotes use operons to organize their genes while prokaryotes do not.
C. • Prokaryotes do not store their genes in a nucleus like eukaryotes do.
D. • Prokaryotes remove exons from mRNA before translation while eukaryotes translate the entire sequence of mRNA.
C. • Prokaryotes do not store their genes in a nucleus like eukaryotes do.
C. • Prokaryotes do not store their genes in a nucleus like eukaryotes do.
To answer this question, we need to compare gene regulation in prokaryotes and eukaryotes. Gene regulation refers to the control of gene expression in an organism. Here's how we can approach finding the correct answer:
A. To determine if eukaryotes transcribe genes in response to environmental stimuli while prokaryotes transcribe genes randomly, we can research the regulatory mechanisms in both types of organisms. While eukaryotes can respond to environmental signals to activate or repress gene expression, prokaryotes predominantly regulate gene expression via operons or other mechanisms.
B. To determine if all eukaryotes use operons while prokaryotes do not, we can look into the organization of genes in these organisms. Operons are a common feature in prokaryotes, where multiple genes are organized together and regulated as a single unit. However, in eukaryotes, gene organization is typically more complex, comprising individual genes that are controlled independently.
C. To determine if prokaryotes do not store their genes in a nucleus like eukaryotes do, we can examine the cellular structures of these organisms. Prokaryotes lack a nucleus and their DNA is found in the cytoplasm, while eukaryotes have well-defined nuclei that contain the majority of their genetic material.
D. To determine if prokaryotes remove exons from mRNA before translation while eukaryotes translate the entire sequence of mRNA, we can investigate the RNA processing mechanisms in both types of organisms. In eukaryotes, pre-mRNA undergoes extensive processing, including the removal of introns and the splicing together of exons, before translation. Prokaryotes, on the other hand, generally lack introns, and their mRNA is typically translated directly without this complex processing.
Therefore, after considering the above options:
The correct answer to the question is C. Prokaryotes do not store their genes in a nucleus like eukaryotes do.
