Worked practice questions

The extra stretch removed as pro-insulin matures is the:

  1. D peptide
  2. C peptide
  3. A peptide
  4. B peptide
Show answer and solution

Correct answer: B. C peptide

1. Insulin is first made as a pro-hormone. 2. The pro-hormone carries an extra stretch. 3. That stretch, the C peptide, is cut out on maturing. _Source: syllabus Biology, Ch 10 'Biotechnology and its Applications'_

  2. 1990
  3. 1983
  4. 1963
Show answer and solution

Correct answer: C. 1983

1. An American company made the two chains separately. 2. It then joined them by creating disulphide bonds. 3. This was done in 1983. _Source: syllabus Biology, Ch 10 'Biotechnology and its Applications'_

Show answer and solution

Correct answer: D. Gene therapy

1. A child is born with a non functional gene. 2. A working copy is delivered into the cells. 3. This correction is called gene therapy. _Source: syllabus Biology, Ch 10 'Biotechnology and its Applications'_
