DNA element with ability to change position iS called

Options

  1. Acistron
  2. Btransposon
  3. Cintron
  4. Drecon

Correct answer

B. transposon

Step-by-step solution

Transposon is a DNA segment or genetic element moving from one chromosome to another. The 'term', was introduced by R W Hedges and A E Jacob in 1974, to 'controlling elements' or jumping genes', discovered by Barbara McClintock (1950) in maize. Cistron is the functional unit of DNA molecules, 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 or those regions of a gene which do not form the part of m R
