Introduction:
Genetic engineering is a field of science that manipulates
the DNA of living organisms to achieve specific outcomes. Its history and scope
are fascinating, spanning various breakthroughs and offering a wide range of
applications.
1.
Historical
Overview:
- 1970’s – Emergence: Genetic Engineering gained momentum in the 1970s with the discovery of Recombinant DNA Technology, allowing the transfer of genes between different organisms.
- 1980’s – First genetically engineered product: The first genetically engineered product, human insulin produced by bacteria, was introduced, making a significant milestone.
2. Key Milestones:
- 1990s
- Human Genome Project: The Human Genome Project, mapping the
entire human DNA, commenced, providing a comprehensive understanding of
our genetic code.
- 2000s
- CRISPR-Cas9: The revolutionary CRISPR-Cas9 gene-editing tool was
developed, offering precise and efficient DNA manipulation.
3. Scope of Genetic Engineering:
- Agriculture:
Genetic engineering plays a vital role in creating crops with enhanced
nutritional content, resistance to pests, and improved yield, contributing
to global food security.
