In recombinant dna technology, a vector is a self-replicating segment of dna, such as a plasmid or viral genome. t/f

True

Explanation: A vector is used to take up foreign DNA into host cell. They are used in recombinant DNA technology (for cloning) because they replicate at a high rate, have antibiotic resistant gene and genetic markers that are used for recognition. Most commonly used vectors are E.coli and smaller circular DNA.

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
