NEETBotanyPlant - Growth and Development
From which source was kinetin originally isolated?
Options
- ACorn kernels
- BCoconut milk
- CAutoclaved herring sperm DNA
- DPlant leaves
Correct answer
C. Autoclaved herring sperm DNA
Step-by-step solution
Search for natural substances with cytokinin-like activities led to the isolation of zeatin from corn-kernels and coconut milk. Cytokinins have specific effects on cytokinesis, and were discovered as kinetin (a modified form of adenine, a purine) from the autoclaved herring sperm DNA.
