Definitions for **"Complement"**

one of at least 20 serum proteins important in immunity and inflammation.

Proteins in the blood that work with antibodies to ward off infection. Patients with active systemic lupus erythematosus can have abnormally low levels of complement proteins in their blood.

a group of 20 proteins which are found in blood. They are involved in the destruction of foreign cells, after the cells have been coated with antibodies.

That which fills up or completes; the quantity or number required to fill a thing or make it complete.

That which is required to supply a deficiency, or to complete a symmetrical whole.

Full quantity, number, or amount; a complete set; completeness.

A compliment.

To compliment.

The event that the given event does not happen.

Definition determined by context: 1] The complementary sequence to a nucleic acid sequence under study. 2] To provide a function that is missing or altered because of a mutational event.

The complement of a nucleic acid sequence replaces each base by its complementary base: adenine (A) by thymidine (T), cytosine (C) by guanine (G), and vice versa. In RNA, adenine is paired not with thymidine but with uracil (U). By convention, DNA and RNA molecules have a consistent orientation (5' to 3') which is used in writing their sequences. To preserve this orientation, the complement of a sequence is written backwards compared to the original. For example, an RNA sequence ACGGUACU has the DNA complement AGTACCGT.

The number of people that serve on board a ship.

The complement of a number is the difference between that number and 10000. . . (to as many zeros as the original number has). In the decimal system, the complement of 354 is 1,000 - 354, or 646. (Binary numbers have corresponding complements as well.) Computers usually subtract by adding the complement of a number, for example, 421 - 354 is computed as 421 + 646, or 1,067. If the machine's registers have only three places, the "1" at the left drops out, giving the true difference 67. A variation of this scheme is to take the difference between each digit and 9, giving the so-called nines complement, instead of the "tens complement" just described. That has the advantage of not requiring any borrowing of digits to form the complement, but a 1 must be added (the so-called end-around carry) to give the correct answer for subtraction.

The entire number of firefighters assigned to a working unit, the number of units assigned to any given alarm, or the amount of like items with similar purposes.

Multiplatform C++ libraries.

two goods are complements if the demand for one (at a given price) decreases as the price of the other increases

a good that is used in combination with another good

a good that is used together with another one

(set theory) The complement of a set A is the set of all elements of the universe which are not in A.

The complement of a language is the set of all instances not in the language. The complement of a complexity class consists of the complement of each language in the class. (Not the set of all languages not in the class!)

A set composed of all elements that are not members of another set.

an expression which combines with a head word to project the head into a larger structure of essentially the same kind

an expression which is directly merged with (and hence is the sister of) a head word, thereby projecting the head into a larger structure of essentially the same kind

See Invert.
