Why do we need to use bacteria for gene cloning?

It is used in the step of transformation, in order to make more plasmid DNA and consequently more gene product of interest

Explanation:

DNA cloning, as a method in molecular biology, is used for the multiplication of gene (or other piece of DNA). It usually includes steps of DNA insertion into plasmid (prokaryotic circular piece of DNA). That plasmid is than introduced into bacteria via process called transformation. Transformed bacteria can produce large amount of a product of a certain gene, because of their fast gene expression.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
