Chapter 1, Problem 3Q

Summary Introduction

To analyze:

The analysis of the fact that application of given experimental model on various other life forms like plants, insects or mammal population, will show the similar results as shown by bacterial population in a changing environment.

Given:

An experiment was conducted to test and evaluate the bacterial resistance towards antibiotics in different conditions. The result shows the survival of different bacterial population, under varying antibiotic concentrations that increased gradually, moderately, and suddenly.

Introduction:

Model organisms taken for the experimental studies should be easily propagated, maintained, bear minimal growth requirement, and also consist some additional specific features such as transparent egg in case of sea urchin, short generation time of Escherichia coli, large progeny size of fruit fly, Drosophila melanogaster etc. Most of these organism’s genomes are completely sequenced and they can be compared with the other organisms because of their common ancestry.
