Utilities Disc is missing

As Disk Utility is an app installed with the OS it cannot be deleted,

what makes you think you deleted it, what did you do.

Open your Applications folder, then the Utilities folder

and you should see Disk Utility there.

Reinstall the macOS:

However this occurred, and if it is indeed missing, reinstall the macOS. Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support. Important: Be certain to create a backup of your Mac prior to all of this. That way, you can have something to restore from the Mac from, should anything go wrong with the reinstall.

When you open the Applications> Utilities folder you do not see this,

As said earlier you cannot delete any apps that installed as part of the OS,

Have you moved it somewhere else.

Have you done a Spotlight search for it.
