Converting a RAID 1 drive to a regular one and booting off of it

I’m using mdadm to manage a RAID 1 array with three disks. Would it be possible to take a single drive from the array (i.e. /dev/sdc), turning it into a regular drive, and then booting another PC off of that one drive?

I also noticed that mdadm didn’t make a partition on /dev/sdc first (like /dev/sdc1) before setting it up as /dev/sdc/md0 instead of /dev/sdc/sdc1/md0 like the other disks that are a part of the array. Does this affect me in any way?

Thank you.
