How you would make a cDNA library from mRNA transcripts manufactured by ovary cells and mass-produce progesterone using bacteria.
1. Producing cDNA's from mRNA's
2. Cloning the cDNA's into bacterial plasmids
3. Introducing the recombinant plasmids into bacteria,
4. Producing and screening a cDNA library and
5. Mass-producing the progesterone hormone.
