Recombinant DNA (rDNA) technology involves joining DNA from different organisms to create new genetic combinations. It allows scientists to modify traits, produce useful proteins, and study gene functions. It forms the foundation of modern **biotechnology and genetic engineering**.
The technique works by identifying a useful gene, cutting it from the donor organism, inserting it into a **vector**, and introducing it into a host cell. The host reproduces, expressing the foreign gene and producing the **desired product**.
Step 1: Isolation of Genetic Material (DNA)
The first step is extracting **pure DNA** from a donor organism. Cells are broken open chemically or mechanically, and DNA is separated from proteins and membranes. This ensures clean genetic material for further manipulation.
Step 2: Cutting DNA at Specific Sites
**Restriction enzymes** (molecular scissors) cut DNA at specific recognition sequences. These predictable cuts produce **“sticky ends,”** which allow easy attachment of foreign DNA fragments. Example: EcoRI, a widely used restriction enzyme in laboratories.
Step 3: Selection and Preparation of the Vector
**Vectors** act as carriers that transfer foreign DNA into host cells. Common vectors include plasmids and bacteriophages. They usually contain selectable markers, replication origins, and specific sites for gene insertion.
Step 4: Ligation of DNA Fragments
The cut donor DNA is joined with the vector DNA using **DNA ligase**, an enzyme that seals the sugar-phosphate backbone. This forms the **recombinant DNA molecule**. Proper ligation ensures stable insertion of the gene into the vector.
Step 5: Introduction of rDNA into Host Cells
The recombinant vector is introduced into suitable host cells, typically bacteria like E. coli. Methods include **transformation** (uptake of DNA), electroporation, and microinjection. The host becomes genetically modified once it accepts the vector.
Step 6: Selection of Transformed Cells

Genetic Engineering Appraisal Committee
Genetic Engineering Appraisal Committee (GEAC)
The Genetic Engineering Appraisal Committee (GEAC) is India’s **apex regulatory body** overseeing the use, release, and approval of **genetically modified organisms (GMOs)**. It ensures that biotechnology applications progress safely without harming human, animal, or environmental health.
Location and Ministry
GEAC functions under the **Ministry of Environment, Forest and Climate Change (MoEFCC)**. The committee derives its authority from rules notified under the **Environment (Protection) Act, 1986**, making it India’s central decision-making body for GMO regulation.
Legal Basis
The statutory foundation of GEAC comes from the **Rules, 1989** (Rules for the Manufacture, Use, Import, Export and Storage of Hazardous Microorganisms/GMOs). These rules legally empower GEAC to approve or reject activities involving genetically engineered products.
Why GEAC Was Created
GEAC was established to create a **structured, science-based system** for assessing new biotechnology products. The aim was to prevent unregulated experimentation while encouraging innovation in agriculture, medicine, and industry through safe genetic engineering practices.
Core Mandate
The central mandate of GEAC is to examine the **environmental and biosafety risks** associated with GMOs. It evaluates scientific data, field trial outcomes, and impact assessments before any GMO moves from laboratory research to larger-scale use.
Functions and Powers
GEAC approves proposals related to **field trials, commercial release, and large-scale production** of GM crops and other engineered organisms. It can impose conditions, suspend approvals, or mandate monitoring measures to ensure compliance with safety standards.
Role in Agricultural Biotechnology
In agriculture, GEAC examines whether GM crops—such as **Bt cotton or Bt brinjal**—are safe for soil health, biodiversity, and non-target organisms. It ensures that research benefits farmers while preventing ecological disruptions.
Role in Medical and Industrial Biotechnology
For health and industry, GEAC evaluates genetically engineered **vaccines, microorganisms used in waste treatment**, or microbial enzymes used in industry. It ensures that these applications meet biosafety guidelines before entering the market.
Multidisciplinary Structure
GEAC includes scientists from biotechnology, ecology, toxicology, agriculture, health sciences, and environmental engineering. Such **multidisciplinary representation** helps in making balanced decisions that combine scientific, social, and ecological perspectives.
Monitoring and Enforcement
Once approvals are given, GEAC oversees compliance through **inspections, progress reports, and biosafety audits**. It coordinates with state committees and institutional biosafety boards to ensure consistent on-ground implementation.
Example for Easy Understanding
For example, before a **GM mustard variety** is released for cultivation, GEAC reviews its allergenicity data, pollen-flow studies, yield comparisons, and environmental impact reports. Only after **multilayer testing** can commercial approval be granted.

Biotechnology Regulatory Authority of India
Biotechnology Regulatory Authority of India (BRAI)
A Proposed but Unenacted Regulatory Framework
Concept and Status
The **Biotechnology Regulatory Authority of India (BRAI)** was a proposed body intended to be the **central regulator** for biotechnology products in India. The BRAI bill was drafted, but it was **never passed into law**, and the authority was therefore not established.
Single-Window Approval
The BRAI was conceived to create a **single-window system** for scientific risk assessment and approval of **all modern biotechnology products**, streamlining the regulatory process from research to commercial use.
Comprehensive Regulation
It was intended to regulate the research, transport, import, containment, **environmental release**, manufacturing, and use of **biotech products and organisms** (including Genetically Modified Organisms or GMOs).
Proposed Structure
The proposed authority would have consisted of a **chairperson**, **full-time members**, and **part-time members** with expertise in various fields of biotechnology to ensure expert evaluation.
Current Status (Crucial Point)
The BRAI bill was **never passed into law**, and consequently, the authority was **not established**. The regulation continues to be managed by the existing multi-agency framework.
Department of Biotechnology (DBT)
The primary government department for promoting **biotechnology research**, developing **policies**, and providing **funding** for the sector under the Ministry of Science & Technology.
Genetic Engineering Appraisal Committee (GEAC)
A statutory body under the Ministry of Environment, Forest and Climate Change ($MoEFCC$) that evaluates and approves the research, development, and **commercial release of Genetically Modified Organisms (GMOs)** to ensure environmental safety.
Drug Controller General of India (DCGI)
An authority under the Ministry of Health and Family Welfare ($MoHFW$) responsible for the regulation and **approval of biopharmaceuticals, vaccines**, and other biotech products intended for **human use**.
India’s biotechnology sector is currently regulated by a **multi-agency structure** (DBT, GEAC, DCGI) rather than a single unified body. Knowledge of this existing framework is essential as the proposed BRAI, designed to create a **statutory, single-window clearance** mechanism, did not materialize.
