Question

Quizplus · Accepted Answer

The enzyme that catalyzes the cutting and resealing of DNA, and is translated from insertion sequences, is called transposase. This enzyme is found in transposable genetic elements or transposons, which are segments of DNA that can move or "transpose" themselves from one location in the genome to another. RNA polymerase is responsible for synthesizing RNA from a DNA template, DNA polymerase catalyzes the synthesis of new DNA strands during replication, DNA ligase joins the sugar-phosphate backbones of DNA fragments together, and DNA helicase unwinds the double-stranded DNA during replication and transcription. None of these enzymes are directly responsible for cutting and resealing DNA through transposition.
