Genetic Engineering, step by step

Classic recombinant DNA technology.

  1. Isolate the geneBy restriction digest, PCR, or reverse transcription from mRNA.
  2. Insert into a vectorPlasmid cut with the same restriction enzyme; ligase seals it.
  3. Transform the hostHeat shock or electroporation makes cells take up the plasmid.
  4. Select transformantsAntibiotic resistance marker; only transformed cells survive.
  5. Express and harvestThe host produces the protein.

Sticky ends

  • Restriction enzymes cut at palindromic sites
  • Staggered cuts leave complementary overhangs
  • The same enzyme on gene and vector makes them join

Human insulin was the first recombinant pharmaceutical, approved in 1982 and produced in E. coli.

Questions about the Genetic Engineering poster

What’s on the Genetic Engineering poster?
5 numbered steps, with a full worked run-through. Classic recombinant DNA technology. Isolate the gene — By restriction digest, PCR, or reverse transcription from mRNA.; Insert into a vector — Plasmid cut with the same restriction enzyme; ligase seals it.; Transform the host — Heat shock or electroporation makes cells take up the plasmid.; Select transformants — Antibiotic resistance marker; only transformed cells survive.; Express and harvest — The host produces the protein.. Human insulin was the first recombinant pharmaceutical, approved in 1982 and produced in E. coli.
Who is the Genetic Engineering poster for?
Genetic Engineering belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning genetics can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Genetic Engineering poster?
Cut, insert, transform, select. The selection step is what makes it workable. A wall chart earns its place by being glanceable from where the work is happening, so Genetic Engineering belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
What other posters go with Genetic Engineering?
CRISPR-Cas9, DNA Sequencing and Epigenetics sit alongside Genetic Engineering in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CRISPR-Cas9DNA SequencingEpigenetics
Is the Genetic Engineering poster free to download and print?
Yes. Genetic Engineering downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Genetic Engineering poster print at?
Genetic Engineering is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Genetic Engineering loses nothing.Printing guide
