Engineering Life: Miracles in Biotechnology - Equity: The Global "Biotech Divide"-advanced

Grade 9CBSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

•

The Biotech Divide refers to the widening gap between developed and developing nations in terms of their capacity to develop, regulate, and access biotechnological innovations such as gene therapy, CRISPR, and molecular diagnostics.

•

Intellectual Property Rights (IPR) and patents can create monopolies that keep the cost of life-saving biotechnological drugs, like insulin or monoclonal antibodies, high. The formula for the total cost of a patented drug can be expressed as Ctotal=Cresearch+Cproduction+CpremiumC_{total} = C_{research} + C_{production} + C_{premium}.

•

Biopiracy involves the commercial exploitation of biological materials or traditional knowledge from indigenous communities without legal authorization or fair compensation. For example, the patenting of properties of the Neem tree (Azadirachta indicaAzadirachta\ indica) or Turmeric (Curcuma longaCurcuma\ longa).

•

Distributive Justice in biotechnology posits that the benefits (BB) and risks (RR) of new technologies should be distributed equitably across the global population, regardless of economic status.

•

Golden Rice is a genetically modified variety of rice (Oryza sativaOryza\ sativa) designed to biosynthesize β\beta-carotene, a precursor of Vitamin AA. While it aims to solve malnutrition, it faces hurdles related to patenting and corporate control.

•

Precision Medicine uses genetic profiling to tailor medical treatment. However, because genomic databases are currently biased toward European ancestries (>75%>75\%), the efficacy of these treatments may be lower for other ethnic groups, further deepening the divide.

💡Examples

Problem 1:

A biotechnological firm spends 100100 million dollars on the R&D (RdR_d) of a new synthetic vaccine. The production cost (PcP_c) per dose is 22 dollars. If they aim to recover the RdR_d costs by selling 1010 million doses, calculate the minimum price per dose (UcU_c) they must charge, ignoring profit margins.

Solution:

Using the formula for unit cost: Uc=RdQ+PcU_c = \frac{R_d}{Q} + P_c Given: Rd=100,000,000R_d = 100,000,000 Q=10,000,000Q = 10,000,000 Pc=2P_c = 2

Uc=100,000,00010,000,000+2U_c = \frac{100,000,000}{10,000,000} + 2 Uc=10+2U_c = 10 + 2 Uc=12U_c = 12

The minimum price per dose is 1212 dollars.

Explanation:

This example illustrates how high R&D costs contribute to the 'Biotech Divide.' If a developing nation cannot afford the 1212 dollar price point, their population remains unvaccinated despite the vaccine being physically available.

Problem 2:

Compare the cost of a patented biotech drug PpatP_{pat} at 500500 dollars with its generic version GgenG_{gen} produced after the patent expires, which costs 2525 dollars. Calculate the percentage reduction in cost.

Solution:

The percentage reduction is calculated as: Reduction %=Ppat−GgenPpat×100\text{Reduction } \% = \frac{P_{pat} - G_{gen}}{P_{pat}} \times 100

500−25475\begin{array}{r} 500 \\ - 25 \\ \hline 475 \end{array}

Reduction %=475500×100\text{Reduction } \% = \frac{475}{500} \times 100 Reduction %=0.95×100=95%\text{Reduction } \% = 0.95 \times 100 = 95\%

The cost is reduced by 95%95\%.

Explanation:

This shows why patent expiration is a critical factor in bridge-building across the Biotech Divide, allowing low-income countries to access advanced medicine through generic manufacturing.
