Complementary - Term used to refer to the natural pairing of the nitrogen bases within DNA and RNA. In DNA, cytosine pairs with guanine and adenine with thymine. In RNA, the thymine is replaced with uracil, which pairs with adenine.

Complementary base pairing is very important in the conservation of the base sequence of DNA. This is because adenine always pairs up with thymine and guanine always pairs up with cytosine.

- Process by which genes on different DNA molecules interact. Usually a protein product is involved, as this is a diffusible molecule that can exert its effect away from the DNA itself.
complement fixation test Immunological method used to detect presence of antibodies that bind (or fix) complement; a standard diagnostic test for many infections.
The complement system directly kills microbes, supplements inflammatory response, and works with the immune response. It complements the actions of the immune system.
The complementary RNA molecule is synthesized according to base-pairing rules, except that uracil is the complementary base to adenine.
Fragment complementarity and splicing

A complementary DNA is a single stranded DNA synthetised from messenger RNA, by reverse transcriptase. It has the complementary base sequence of that mRNA. It must be distinguished from the complementary strand of a double stranded DNA.

Is the genetic complement of a neuron different from a skin cell or muscle cell?
This question was first approached by Briggs and King in the 1950s through nuclear transfer experiments in frogs.

In the DNA molecule, they are linked to one another in pairs of long chains, where each member of the pair is complementary to the other. This double-stranded chain is itself twisted into a double helix.
Late in telophase, new centrioles are formed adjacent to existing copies of the organelles so that each daughter cell contains a complementary centriole pair.
Okay, so an anticodon is a three-letter sequence that's complementary, or matches up, to the codon sequence found in the RNA. And the RNA, typically a messenger RNA, codes for proteins.
