Introduction to Biotechnology module quiz: definition, history, industry and units (SEAB O-Level Applied Subject) quiz

The study of chemical reactions that do not involve living things

The use of living organisms, or parts of them such as cells and enzymes, to make useful products or provide services

The use of machines to replace all human labour in factories

The study of the Earth's rocks, minerals and fossils

Bacteria are involved in biotechnology

Yeast is a microorganism

Bacteria carrying the human insulin gene produce insulin to treat diabetes

Insulin is a hormone made in the pancreas

Whole microorganisms such as bacteria and yeast

Enzymes extracted from living things

Purely synthetic chemicals with no biological origin

Plant or animal cells grown in culture

Inserting a human gene into a bacterium

Using yeast to ferment sugars into ethanol and carbon dioxide in brewing

Sequencing a person's whole genome

Cutting DNA with a restriction enzyme

Modern biotechnology never uses microorganisms

Modern biotechnology deliberately reads and changes genes using recombinant DNA technology

Traditional biotechnology is more expensive

Traditional biotechnology only works in hospitals

It is only ever practised by biologists working alone

It combines biology, chemistry and engineering, each contributing a different part of the work

It does not rely on any scientific knowledge

It is taught only at universities

Manufacturing, then research and development, then sale

Research and development, then manufacturing and quality control, then regulation and sale

Sale, then regulation, then research

Quality control, then research, then disposal

Regulatory affairs specialist

Bioprocess engineer

Sales representative

Quality assurance auditor
