DNA element with ability to change position is called

  • cistron

  • transposon

  • intron

  • recon

Solution

B.

transposon

Transposon is a DNA segment or genetic element moving from one chromosome to another. It was introduced by R W Hedges and A E Jacob in 1974.

Cistron is the functional unit of DNA molecules as it codes for a particular gene product.

Recon is the cross- over unit or it is segment of DNA which participates in crossing over.

Introns are the interrupted genes which do not form the part of mRNA and are further removed from primary mRNA during gene expression in eukaryotes.
