e. Production of mRNA from the cloned gene

Explanation:

During cloning in a bacterial host the recombinant DNA is replicated but not necessarily transcribed to mRNA. The promoters are controlled so that trancription and translation of the gene may occur under certain conditions. For example addition of an inducer such as IPTG into bacterial media inducing protein expression via promoter binding.
