4. (Genetics) genetics Also called: cloning vector an agent, such as a bacteriophage or a plasmid, by means of which a fragment of foreign DNA is inserted into a host cell to produce a gene clone in genetic engineering
5. (Navigation) the course or compass direction of an aircraft
6. any behavioural influence, force, or drive
7. (Navigation) to direct or guide (a pilot, aircraft, etc) by directions transmitted by radio
8. (Aeronautics) to alter the direction of (the thrust of a jet engine) as a means of steering an aircraft
[C18: from Latin: carrier, from vehere to convey]
1. a quantity possessing both magnitude and direction, as force or velocity. Compare scalar (def. 4).
2. the direction or course followed by something, as an airplane.
a. something or someone, as a person or an insect, that carries and transmits a disease-causing organism.
b. any agent, as a mutated virus, that acts as a carrier or transporter.
a. to guide (an aircraft) in flight by issuing appropriate headings.
b. to change direction of (the thrust of a jet or rocket engine) in order to steer the craft.
[1695–1705; < Latin: one that conveys, derivative of vehere to carry]
vec•to′ri•al (-ˈtɔr i əl, -ˈtoʊr-) adj.
1. A quantity, such as velocity or change of position, that has both magnitude and direction. Compare scalar.
2. An organism, such as a mosquito or tick, that spreads disease-causing microorganisms from one host to another without harm to itself.
Past participle: vectored
A quantity that is direction as well as magnitude.
