is a 2-strand
. Each strand is essentially a string

). The reverse complement
of a sequence
is what appears on the opposite DNA strand; you get it by reversing the sequence and taking complementary letters.
So it's not a notion made-up by bored molecular biologists; it's really an inherent part of nature.
