Spermatogenesis is the process of forming sperm cells by meiosis (in animals, by mitosis in plants) in specialized organs known as gonads (in males these are termed testes). After division the cells undergo differentiation to become sperm cells.
The Dracula of fiction lived in a place that was based on Bran Castle in Transylvania. Bram Stoker never visited Romania. He depicted the imaginary Dracula's castle based upon a description of Bran Castle that was available to him in turn-of-the-century Britain.
Draculaâs Castle in Transylvania has gone up for sale. Nestled in the Romanian countryside, the property is a tasty investment, and with the closest town, Brasov, some miles away, thereâs plenty of peace and quiet, meaning youâll be able to sleep for a thousand years â or least get a peaceful, lazy Sunday.
