Altering patterns of gene expression in prokaryotes would likely increase a prokaryote's survival by _______.

• A. Organizing gene expression, so that genes are expressed in a given order.
• B. Allowing each gene to be expressed an equal number of times.
• C. Allowing a prokaryote to adjust to changes in environmental conditions.
• D. Allowing environmental changes to alter a prokaryote's genome.

Answer: (C)

Verified step by step guidance

1. Understand that prokaryotes, such as bacteria, often live in environments that can change rapidly. Their ability to survive depends on how well they can adapt to these changes.
2. Recognize that gene expression in prokaryotes is tightly regulated and can be altered in response to environmental signals. This regulation allows them to express certain genes only when needed, conserving energy and resources.
3. Consider that altering patterns of gene expression enables prokaryotes to quickly respond to environmental changes, such as nutrient availability, temperature shifts, or the presence of toxins.
4. Realize that by adjusting gene expression, prokaryotes can produce proteins that help them survive under new conditions, such as enzymes to metabolize different nutrients or proteins to protect against stress.
5. Conclude that the ability to alter gene expression in response to environmental changes is crucial for prokaryotic survival, as it allows them to adapt and thrive in diverse and changing environments.
