No it's not. It's also being used if for example the reply for a query
becomes too large.

No - if the nameserver is a public one (serving any domain) you should
leave port 53 - both TCP and UDP - open. You might of course limit who can
do zone transfers if you feel like it, but that should _not_ be done by
just blocking port 53 TCP. It should be done by for example the
allow-transfer statement in named.conf.
