A modified form of adenine, a purine

Options

  1. Awas discovered from autoclaved herring sperm DNA
  2. Bis naturally found in plants and helps in preventing apical dominance
  3. Cwas isolated from corn kernels and coconut milk
  4. Dis a synthetic compound which promotes cell division in plants

Correct answer

A. was discovered from autoclaved herring sperm DNA

Step-by-step solution

N6-furfurylamino purine is a modified form of adenine called kinetin. It was discovered from autoclaved herring sperm DNA. It is not naturally found in plants. It has cytokinin activity and used in plant tissue culture along with low auxin to promote the formation of the stem in callus. Zeatin was isolated from corn kernels and coconut milk.
