The first MAJOR recombinant DNA pharmaceutical, released commercially in 1982, was:

  1. Recombinant human growth hormone
  2. Hepatitis B vaccine (recombinant)
  3. Erythropoietin (kidney patients)
  4. Recombinant human insulin (Humulin)
Show answer and solution

Correct answer: D. Recombinant human insulin (Humulin)

HUMULIN (Eli Lilly, 1982) was the first commercial rDNA drug: human insulin produced by genetically modified E. coli. Before that, insulin came from animal pancreases. Hepatitis B recombinant vaccine came later (1986).

In gel electrophoresis DNA fragments move towards the:

  1. Cathode
  2. Buffer
  3. Matrix
  4. Anode
Show answer and solution

Correct answer: D. Anode

1. DNA carries a negative charge on its backbone. 2. A negative molecule is pulled to the positive electrode. 3. That electrode is the anode. _Source: syllabus Biology, Ch 9 'Biotechnology : Principles and Processes'_
