Which of the following best describes Recombinant DNA? A. A bacterial plasmid with a target gene inside it.
OB. A bacterial gene with a target plasmid inside it.
C. DNA that has been copied into an mRNA strand.
D. A plasmid and restriction enzyme.

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

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
