Can you buy BNB on Binance?

Could you possibly clarify for me, is it feasible to purchase BNB tokens directly through the Binance platform? I've been hearing a lot about the utility of BNB and am interested in adding it to my portfolio. However, I'm not entirely certain about the specific steps involved in the purchase process. Could you provide some insight into this matter? Additionally, are there any specific requirements or prerequisites that I need to fulfill in order to make such a purchase? Thank you for your assistance in this matter.
