An mRNA transcript can be used to create a cDNA.

The viral enzyme reverse transcriptase catalyzes the assembly of a complementary DNA strand on the mRNA transcript.

Enzymes remove the mRNA to produce a single-stranded cDNA.

Double-stranded cDNA is synthesized using the single strand as the template.

The result is a double-stranded cDNA "copied" from the mRNA transcript.

This cDNA can be inserted into a plasmid, and the plasmid inserted into a bacterium.

The bacterium then can use the cDNA instructions for synthesizing a protein of interest.
