In maize, a Ds or Ac transposon can alter the function of genes at or near the site of transposon insertion. It is possible for these elements to transpose away from their original insertion site, causing a reversion of the mutant phenotype. In some cases, however, even more severe phenotypes appear, due to events at or near the mutant allele. What might be happening to the transposon or the nearby gene to create more severe mutations?

Hello everyone here We have a question asking the transpose zones which moved by copy and paste mechanism and differ from other transpose owns because the copy is made of RNA instead of DNA are called what? So normally we have a D. N. A copy being made from RNA. But in this case we have D. N. A. Being turned into an RNA copy. And this is happening with the use of the enzyme reverse transcriptase to generate a DNA coffee of the RNA for it to be inserted in the new location of the genome and the transpose on that does this is called retro transpose on as the name kind of clues us in on. So our answer is a retro transpose seasons. Thank you for watching. Bye.
