Answer:
The correct answer will be-true
Explanation:
E.coli is a prokaryote which is used by the geneticist and the molecular biologist to study the basic mechanisms of the molecular biology like DNA replication, gene expression and others.
This has been made possible as the E.coli is a simple organism which can be easily cultured in the laboratories.
Also, the small size of the bacterium and the small size of the bacterial genome which is 4.2 million bp provides an advantage to study the concepts of the molecular biology.
Thus, true is the correct answer.
