Question

Foreign DNA is also called
A. Vehicle DNA
B. Passenger DNA
C. r-DNA
D. Vector DNA

Answer 1

Hint:- A vector is a DNA molecule used in molecular cloning as a vehicle to transport foreign genetic material artificially into another cell where it can be repeated and/or expressed.

Complete answer:
In an argument which claimed that evolution eventually worked at the level of genetic information and not at the level of populations of organisms, species, or even cells, the concepts of replicators and vehicles. Replicators refer to genetic knowledge packages which are responsible for any productive vehicle phenotype. A cell, a multicellular organism, may be a vehicle itself. The continuous struggle inside and between prokaryotic vehicles for life modifies the replicators' phenotypes. In order to understand the functions and evolutionary trajectories of viruses, bacterial cells and plasmids in various ecological contexts and under various selection pressures, a lot of theoretical and experimental work has been performed.
With membranes, energy, and all else, a cell vehicle denotes a prokaryotic cell but excludes any genetic material. A single vehicle and its immediate descendant arising by cell division are indicated by the cell-vehicle lineage. A replicator is any sufficiently discrete set (which seems worth naming) of genetic material that uses the cell vehicle for its preservation and propagation. In nature, plasmids harbor an operon containing many genes whose protein products function in a particular biochemical pathway. Besides cellular defense, virulence, and metabolism, plasmid-borne genes have been shown to be involved in antibiotic resistance. The presence of the plasmid may thus offer a survival advantage to the host cell in its environment. Recombinant DNAs, on the other hand, are man-made, rather than natural being.We use genetic vectors to deliver foreign DNA into the receiving cells. They can autonomously replicate and usually provide features to promote DNA manipulation. They are often referred to as international DNA vehicles.
Hence, the correct answer is (a) Vehicle DNA.

Note:- In the bacterial sense, to distinguish it from the bacterium 's DNA, which is called the host DNA, the fragment of DNA from the human genome (or the genome of another organism being studied) is referred to as foreign DNA.
