Question

These movable segments are now called A) DNA sequencing. B) recombinant DNA. C) transposons or jumping genes. D) transgenic or McClintock plasmids.

Answer 1

c) transposons or jumping genes.

Answer 2

Answer: The correct option is c. transposons or jumping genes.

Barbara McClintock while studying the genetic inheritance in corn plants found that DNA segments can change position in genome or can move from one chromosome to another. The mobile genetic elements or the transposons are also called jumping genes. The transposons are capable of moving to different positions in a single cell genome. The transposons are responsible for causing mutations or change the amount of DNA of the cell.
