Genetically Modified Organisms are engineered for disease resistance, higher yields, and environmental sustainability.
Define Micropropagation.
A tissue culture method used to produce thousands of genetically identical plants rapidly.
What is Totipotency?
The ability of plant cells to regain the capacity to develop into a whole organism from any part or explant.
Application of Bt Toxin.
Cry proteins from Bacillus thuringiensis are used to create pest-resistant crops like Bt cotton.
Importance of Gene Therapy.
A technique to correct defective genes; used to treat genetic disorders like ADA deficiency.
Gene Cloning Basics.
Involves inserting a gene of interest into plasmids and introducing into host cells like E. coli for protein production.
Use of PCR in Diagnosis.
Polymerase Chain Reaction amplifies DNA to detect pathogens effectively at low concentrations in samples.
What is ELISA?
Enzyme Linked Immuno-sorbent Assay detects antigens or antibodies to help diagnose infections.
Define Transgenic Animals.
Animals genetically modified to express extra genes; useful for disease study and medical products production.
Applications of Tissue Culture.
Used for large-scale plant propagation and recovering virus-free plants from diseased stock.
Explain Somatic Hybridization.
