What this dot point is asking

This outcome asks you to explain why biotechnology is regulated and why informed consent matters. These are the safeguards that sit around the science: regulation protects the public from unsafe products, and informed consent protects individuals' right to decide about their own bodies and genetic information. A good answer gives the reasons and how each works.

The answer

Why biotechnology is regulated

Biotechnology products can affect human health, food safety and the environment, so they are regulated to:

  • Protect the public from unsafe or ineffective products.
  • Ensure products are properly tested before use.
  • Build public trust in the technology.

Without regulation, harmful or untested products could reach people, and trust in the whole field would collapse.

How a product is approved

A new product must pass through a process before it can be sold:

  1. Testing. Laboratory tests, and for medicines, clinical trials on people, to check safety and effectiveness.
  2. Review. The evidence is submitted to a regulatory authority, which examines it.
  3. Approval. Only if the evidence is satisfactory is the product approved for sale.
  4. Monitoring. The product may continue to be monitored after approval.

GM foods are assessed for safety in a similar way before approval.

What informed consent means

Informed consent means a person agrees to a procedure, such as a genetic test or a treatment, only after they have:

  • been given clear information about what it involves, its benefits, its risks and the possible consequences;
  • understood that information; and
  • agreed freely, without being pressured.

Why informed consent matters

  • It respects a person's right to decide about their own body and information (their autonomy).
  • Genetic results can have serious implications, for example revealing a disease risk or affecting relatives, so the person must understand them before agreeing.
  • It maintains trust between people and healthcare or scientists.

Examples in context

Example 1. Approving a vaccine. Before a vaccine is used, it passes through laboratory tests and clinical trials, and the evidence is reviewed by a regulatory authority that decides whether to approve it. This protects the public and shows regulation working in practice.

Example 2. Consent in genetic screening. Before a genetic screening test, the person is given clear information and must freely agree, because the results can be life-changing and may affect relatives. It shows informed consent protecting an individual's right to decide.

Q1. State two reasons biotechnology products are regulated. [2 marks]

  • Cue. To protect the public from unsafe or ineffective products, and to ensure products are properly tested (building public trust is also acceptable).

Q2. Explain what informed consent means. [2 marks]

  • Cue. A person agreeing freely to a procedure only after being given, and understanding, clear information about what it involves and its benefits, risks and consequences.

Q3. Give one reason informed consent is especially important in genetic testing. [1 mark]

  • Cue. Genetic results can have serious implications, such as revealing a disease risk or affecting relatives, so the person must understand them before agreeing.

Original6 marksExplain why biotechnology products such as medicines and GM foods are regulated, and outline how a new product is approved before it can be sold.
Show worked answer →

Examiners want the reasons for regulation and an outline of the approval process.

Biotechnology products are regulated because they can affect human health, food safety and the environment. Regulation protects the public from unsafe or ineffective products, ensures products are properly tested, and builds public trust in the technology.

To be approved, a new product must be tested thoroughly. For a medicine, this means laboratory tests followed by clinical trials on people to check it is safe and effective. The evidence is submitted to a regulatory authority, which reviews it and decides whether to approve the product. Only after approval can it be sold, and it may continue to be monitored afterwards. GM foods are similarly assessed for safety before approval.

What markers reward: regulation to protect health, food safety and the environment and to ensure testing and trust, and an approval process of thorough testing (including clinical trials for medicines), review of evidence by a regulatory authority, approval before sale, and possible ongoing monitoring.

Original5 marksExplain what is meant by informed consent and why it is important in genetic testing and medical treatment.
Show worked answer →

The answer should define informed consent and explain its importance.

Informed consent means that a person agrees to a procedure, such as a genetic test or treatment, only after they have been given clear information about what it involves, its benefits, its risks, and the possible consequences, and they understand this information and agree freely without being pressured.

It is important because it respects the person's right to make decisions about their own body and information. In genetic testing, results can have serious personal implications, for example revealing a risk of disease or affecting relatives, so the person must understand these before agreeing. It also maintains trust between people and healthcare or scientists.

What markers reward: informed consent as agreement after being given and understanding clear information about the procedure, its benefits, risks and consequences, given freely; and its importance in respecting autonomy, especially given the serious implications of genetic results, and maintaining trust.
