The breaks in the strands are joined using

a circular piece of doublestranded DNA called

The introduction of a new DNA segment (gene) into a bacterial cell requires a DNA carrier called

intact and infective virus particle

used to break DNA up into fragments of known size and nucleotide sequence, which can then be spliced together with DNA ligases.

Restriction enzymes act at sites on DNA called

found in a wide variety of bacterial cells, catalyze the cleaving of DNA molecules, except for a few specific types.

produced when segments of DNA from one organism are introduced into the genetic material of another organism
