With DNSSEC, it’s not DNS queries and responses themselves that are cryptographically signed, but rather DNS data itself is signed by the owner of the data. Every DNS zone has a public/private key pair. The zone owner uses the zone’s private keyto sign DNS data in the zone and generate digital signatures over that data.
