Question

Laboratory strains of E. coli are desirable hosts because?

1) it is easy to grow
2) its genetics is well known
3) it is especially able to express foreign genes
4) it has known phenotypic characteristics
5) All of the choices are correct

Answer 1

Laboratory strains of E. coli are desirable hosts due to their ease of cultivation, well-known genetics, ability to express foreign genes, and known phenotypic characteristics.

Step-by-step explanation:

Laboratory strains of E. coli are desirable hosts for several reasons. First, it is easy to grow in a laboratory setting, which makes it convenient for experiments and research. Second, its genetics is well known, meaning scientists have a good understanding of its DNA and how it functions. Third, E. coli is especially able to express foreign genes, making it useful for genetic engineering and protein production. Lastly, it has known phenotypic characteristics, which allows researchers to study specific traits and behaviors of the bacterium.
