How to buy Doge on Coinbase?

As a cryptocurrency enthusiast, I'm curious about the process of purchasing Dogecoin, or "Doge," on Coinbase. Could you provide a step-by-step guide on how to navigate the Coinbase platform to acquire Dogecoin? I'm particularly interested in understanding the verification process, funding my account, locating Dogecoin in the trading options, and executing the purchase. Additionally, I'd like to know if there are any fees associated with the transaction and if there are any security measures I should take to protect my investment. Thank you for your assistance in navigating this process.
