Question

Quizplus · Accepted Answer

In recombinant DNA methods, a vector refers to a carrier molecule that helps transfer foreign DNA into a host cell. The most commonly used vectors in molecular biology are plasmids, which are small, circular DNA molecules that can be easily manipulated in the laboratory and replicate independently inside the host cell. Vectors can also be viral genomes or artificial chromosomes. The other options listed (enzyme, sticky end, SNP marker) are all components or tools in DNA manipulation but do not refer specifically to vectors.
