A is false, B is true

Statement A is false. Cytokinins help to promote cell division in plant cells, not inhibit it. Cytokinins are a group of plant hormones that play a significant role in promoting cell division and growth. 

Statement B is true. Cytokinins were discovered as kinetin (a modified form of adenine, a purine) from the autoclaved herring sperm DNA.
