Can someone explain in depth how dns functions in a domain controller and why it is a part of a domain controller ...

DNS translates IP addresses into Names. In this mostly internal network IP address to names. So 192.168.0.11 becomes Server2.

Active Directory needs DNS to be running or it will not work.

Hey @Noe-Sosa ,

Essentially Domain Controllers need DNS to translate names to IP addresses. Active Directory uses Domain Name System (DNS) name resolution services to make it possible for clients to locate domain controllers and for the domain controllers that host the directory service to communicate with each other.

This enables easy integration of the Active Directory namespace such as something like noesosarocks.com into an existing DNS namespace. Because computers need IP addresses to contact and communicate with each other, DNS allows us to use names for servers and other objects that would be impossible for someone to remember the particular IP address of that server or object. DC1.noesosarocks.com is easier to identify than say 172.16.23.45/24

Hope that helps!
