Definition: This is a DNA molecule into which foreign DNA may be inserted. The new DNA replicates when inserted into an appropriate cell.

DNA vector.

Explanation:

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical condition.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

DNA vector can be defined as a DNA molecule into which foreign DNA may be inserted. The new DNA replicates when inserted into an appropriate cell.

Basically, DNA vectors are mainly used in molecular cloning to artificially carry a desired DNA sequence into another cell known as the host cell.
