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.

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
