Worst Flower

The world’s largest flower is also one of the worst smelling flowers. Rafflesia Arnoldii is often over 3 feet wide and its petals are almost an inch thick. You wouldn’t want it in your garden, however, because it smells like a rotting animal. The flower is attempting to attract flies for pollination.

Composition of DNA

It seems amazing that the little-tiny chains of DNA in each cell of your body contain the complete blueprints for your whole self. Even more amazing, scientists have determined that only 1 percent of that DNA seems to contain all the information for building, repair, fighting diseases and so on, and the other 99 percent has no known function!
