By default, tcpdump captures only the first 68 bytes of a packet; I have
a capture here with a simple DNS query, and the total length of the
packet is 71 bytes.

To capture more data, use the "-s" flag, and specify the maximum number
of bytes to capture; "-s 65535" should capture the entire packet, and,
on current versions of tcpdump, "-s 0" should also do so (0 being a
special value meaning "the entire packet").

"Which port" in what sense?  It's not any well-known or reserved port, as
far as I know; that's why it's printed as a number.  It's just the port
that was chosen by the OS on which the DNS client (resolver) was
running, so that the traffic to the DNS server (the first packet) was
sent from that port and the reply to the DNS server (the second packet)
was sent to that port.
