E)coli and many other bacteria of the human gut need to have fine-tuned regulation of gene expression in order to _____.
A)replicate their DNA
B)metabolize any nutrient
C)effectively compete for space and nutrients
D)grow
E)evolve

Question

Quizplus · Accepted Answer

The human gut is a competitive environment, with many different species of bacteria competing for space and nutrients. In order to effectively compete, these bacteria need to fine-tune their regulation of gene expression to metabolize nutrients and grow efficiently. This allows them to outcompete other bacteria and survive in the gut environment. Replicating DNA and evolving may be important for bacteria survival and adaptation, but neither requires fine-tuned regulation of gene expression.
