Question

______ organism was used to produce recombinant insulin.

(a) Cyanobacteria

(b) E.coli

(c) Saccharomyces cerevisiae

(d) B. subtilis

The question was posed to me in quiz.

I'd like to ask this question from Biotechnological Applications in Medicine: Genetically Engineered Insulin in chapter Biotechnology and its Applications of Biology – Class 12

Answer 1

Correct answer is (b) E.coli

To explain: The first recombinant insulin was constructed by using E.coli. It was developed by Lilly Company. E.coli was used because it has a large circular plasmid that can act as a vector, requires less growth time and can be easily grown in a laboratory.
