This version is not the exact complementary sequence but adopts the same structure as the sense (genomic) strand.

If a creature containing one of these template sequences encounters another creature with the complementary sequence, they interact.

There is a simple constructive method to create arbitrarily long complementary sequences.

So which is it, complimentary sequences or complementary sequences?

For example, dsRNA may be synthesized to have a specific sequence complementary to a gene of interest.

Therefore, the complementary sequence will be to the sense strand.

For other values of the procedure for finding complementary sequences is not as straightforward.

Since the two reverse complementary sequences will fold and base-pair with each other, the sequence of bases between them form a hairpin loop.

Examples include the Shapiro polynomials, which give rise to complementary sequences of length a power of 2.

Strands of complementary sequence will bind tightly to each other.
