Microinjection is the standard technique for creating transgenic animals by directly injecting DNA into the pronucleus of a fertilized egg, allowing integration into the genome.
Major concerns include the development of resistance in target insects, impacts on non-target beneficial organisms, and long-term ecological effects of Bt crop cultivation.
Reverse transcriptase, derived from retroviruses, synthesizes complementary DNA (cDNA) from an mRNA template, essential for expressing eukaryotic genes in prokaryotes.
Agrobacterium tumefaciens naturally transfers its T-DNA into plant cells, making it an excellent natural vector for creating transgenic plants.
CSIR-Institute of Genomics and Integrative Biology (IGIB) has been at the forefront of developing CRISPR-based diagnostic tools for various diseases in India.
Chimeric genes combine regulatory sequences from one organism with coding sequences from another, creating novel genetic constructs for transgenic organism development.
RNAi uses small interfering RNAs (siRNA) or short hairpin RNA (shRNA) to target and degrade specific mRNA molecules, leading to gene silencing.
Ex vivo gene therapy involves isolating cells from the patient, modifying them genetically outside the body, and then reintroducing them, reducing immune reactions.
DNA fingerprinting uses variable DNA regions to create unique profiles for identification in forensics, paternity testing, and population studies.
Recombinant human insulin produced through genetic engineering is a major medical biotechnology application, revolutionizing diabetes treatment.
