Depending on the purpose of the cloning procedure, the vector may assist in multiplying, isolating, or expressing the foreign DNA insert.
How do vectors work?
A vector is a way to take a sequence of DNA, usually, and introduce it into another place. So what vectors do is allow you to propagate the DNA you're interested in, in the organism you've chosen to propagate it in. So the simplest one is the origins of recombinant DNA technology: They made copies of RNAs, and they were able to insert these into what is known as plasmids. Now, plasmids are kind of mini-bacterial chromosomes. They have a way to replicate themselves, and what makes it work is they also carry one or two genes on them that make them resistant to specific antibiotics. So if you can insert the gene you're interested in into this plasmid, you can select for the bacteria that have picked up that plasmid by growing them on an antibiotic that, if they haven't picked it up, would kill them. So that plasmid is a vector for taking a particular DNA sequence into a bacteria. And then you can isolate one colony of bacteria and clone that, grow that clone up, and that's how you would propagate that. There are other vectors that are larger and will have multiple sites of origins of replication, and these are known as bacterial artificial chromosomes, and they can handle much larger pieces of DNA. There are yeast artificial chromosomes that allow very large fragments of DNA to be grown in yeast cells. And recently, human artificial chromosome have been developed that allow enormous pieces of DNA to be introduced and propagated into human cells. So vector is really just a means to take a piece of DNA that you're interested in and insert it, and select for it, and identify it in the organism that you want to propagate it in.

What is a vector?
A related definition is the haematophagous arthropoddefinition (definition #4), which defines vectors only as blood-feeding arthropods such as mosquitoes, ticks, sandflies, tsetse flies and biting midges [25]. Such arthropods generally also fall within the micropredator definition above, with the exception of species that feed on only a single host in their entire lifetime, such as louse flies (Hippoboscidae) and one-host ticks (such as Rhipicephalus microplus). This definition is used explicitly by several groups including the European Centre for Disease Prevention and Control [26] and the Intergovernmental Panel on Climate Change [27], and other sources either implicitly adopt this definition [28,29] or explicitly cite a broader definition but go on to discuss only examples falling under this definition [30]. A weakness with such a definition is that it may detract attention from useful insights from species playing essentially equivalent roles in non-vertebrate hosts, for example sap-feeders (aphids) or haemolymph feeders (Varroamites). In addition, other large groups of vertebrates, such as rodents, which also spread pathogens through their saliva (or other excreta, albeit generally by a different route from percutaneous penetration), and that are often considered vectors, are also excluded.
What is vector in biology?
One of the broadest definitions defines a vector as any organism (vertebrate or invertebrate) that functions as a carrier of an infectious agent between organisms of a different species [19]. This includes organisms playing a purely mechanical role in transmission (e.g. Muscaflies in the transmission of Chlamydia trachomatis, the causative agent of trachoma). Some authors have gone further and extended the definition to include fomites (the biological + physical definition; definition #1)—inanimate objects capable of carrying infectious material and transferring it between hosts, such as syringes [20] and paper money [21]. Although it seems incongruous to group fomites together with biological agents of transmission, which can experience strong ecological and evolutionary interactions with the pathogen, from a public health perspective this definition may be relevant to disease management and prevention. Alternatively, a relatively common way to assign vector status to a particular host in a multi-host system is with reference to their involvement in the transmission of pathogens of human relevance (anthropocentric, definition #2). These may be pathogens that directly infect humans, for example, ‘[v]ectors are living organisms that can transmit infectious diseases between humans or from animals to humans' [22] (and [23], with slightly different wording); under this definition, any non-human host connected to human hosts by one or more transmission modes is a vector. While the motivation behind such a definition seems obvious, it clearly has problems if applied rigidly; for example, it leads us to the slightly illogical consequence that under this definition a mosquito transmitting West Nile virus (WNV) from a wild bird to a human is a vector, while a mosquito transmitting WNV between wild birds is not. A slightly more flexible interpretation would be that any host capable of transmitting a pathogen of importance to humans to or between one or more hosts is considered to be a vector.
What are vector borne diseases?
Many parasites and pathogens responsible for some of the most important diseases in humans, agriculture and nature are routinely described as ‘vector-borne’. These include emerging parasites and pathogens such as dengue virus throughout the tropical world [1], West Nile virus in North America [2] and Europe [3], Crimean–Congo haemorrhagic fever virus in Turkey [4], hantavirus in Europe [5], bluetongue virus in Europe [6], zika virus in South America [7], Lyme borreliosis in Europe [8] and chikungunya virus in the Caribbean [9]. Almost 20% of human deaths are caused by infectious diseases that are described as vector-borne, chiefly malaria, yellow fever, leishmaniosis, trypanosomiasis, Chagas' disease and Japanese encephalitis [10], and such diseases are predicted to present a growing threat in the near future [11]. However, different definitions of a vector are used in different fields. For instance, the term is universally applied to haematophagous arthropods, such as Ixodesticks that transmit Borrelia burgdorferior Aedesmosquitoes that transmit dengue virus, but the term ‘vector’ has also been applied to badgers transmitting Mycobacterium bovis[12–14], dogs transmitting rabies virus [15], snails transmitting Schistosomaflatworms [16,17] and rodents transmitting hantaviruses [18]. Clearly a large number of definitions of ‘vector’ are currently being used, and the question in any multi-host system should be to ask when and why a particular host in that system warrants designation as a ‘vector’.
Is a vector a host?
A vector could be considered just another host in a parasite's life cycle, and applying some of the above definitions to multi-host systems can result in the classification of two or more different groups as ‘vectors', implying that it is appropriate to use similar ways to represent them in mathematical models (as also discussed in [35]). Here, we discuss when this is a sensible simplification and also when it may obscure or conceal important epidemiological and ecological processes.
Is a vector a pathogen?
Many important and rapidly emerging pathogens of humans, livestock and wildlife are ‘vector-borne’. However, the term ‘vector’ has been applied to diverse agents in a broad range of epidemiological systems. In this perspective, we briefly review some common definitions, identify the strengths and weaknesses of each and consider the functional differences between vectors and other hosts from a range of ecological, evolutionary and public health perspectives. We then consider how the use of designations can afford insights into our understanding of epidemiological and evolutionary processes that are not otherwise apparent. We conclude that from a medical and veterinary perspective, a combination of the ‘haematophagous arthropod’ and ‘mobility’ definitions is most useful because it offers important insights into contact structure and control and emphasizes the opportunities for pathogen shifts among taxonomically similar species with similar feeding modes and internal environments. From a population dynamics and evolutionary perspective, we suggest that a combination of the ‘micropredator’ and ‘sequential’ definition is most appropriate because it captures the key aspects of transmission biology and fitness consequences for the pathogen and vector itself. However, we explicitly recognize that the value of a definition always depends on the research question under study.
Is HIV vector borne?
Furthermore, a definition of ‘vector’ that suggests that HIV is vector-borne but B. burgdorferiis not is unlikely to satisfy most people. The relationship between population density and transmission is therefore likely to be acceptable as a qualification for defining a vector only in combination with other traits.
