Changing desktop environment

Hello,
Before Ubuntu Mate I’ve tried Linux Mint,and one more distro that i can’t remember,so… pretty much i am quite new to linux.
Meanwhile,i got quite bored of the mate interface,so i was curios if i can switch to Ubuntu desktop interface,which i guess its … Gnome?

The normal interface for Ubuntu is Unity but you can install the full Gnome DE over it if you want to without a new install and select your desktop at the login window.

See here for a few ideas about installing Gnome:

That was very useful,thank you very much! :]
