01 / LESSON

Build the explanation.

  • Explain how cloned genes produce antigens and therapeutic proteins.
  • Compare monoclonal-antibody and nucleic-acid-probe diagnostics.
  • Distinguish ex vivo from in vivo gene therapy and their vector challenges.

02 / NOTES

The essentials, in one place.

  • Recombinant hosts express selected genes to make useful proteins.
  • Vaccines present antigens; antibodies recognise antigens.
  • Monoclonal antibodies recognise molecules, while probes recognise complementary sequences.
  • Gene therapy must solve delivery, specificity, expression and safety together.

03 / ACTIVITY

Test the idea by changing something.

Predict the result first, run the activity, then explain what changed and why.

04 / DIAGRAM

Make the connections visible.

A recombinant-protein workflow
01Select gene

Choose the coding sequence for the product.

02Build vector

Join the gene to regulatory DNA in a carrier.

03Transform host

Introduce recombinant DNA into suitable cells.

04Select and grow

Clone productive cells in controlled culture.

05Purify product

Separate and verify the therapeutic protein.

Producing the protein is only part of the process; purity, activity and safety must also be established.

Cover the labels, redraw the sequence or comparison, and explain each connection aloud.

05 / QUIZ

Retrieve before you reread.

Build a timed test from this chapter’s 100 practice questions. Questions and options are shuffled; missed answers feed your revision notebook.
