Cells use a molecule called Choose...
to store and release energy like a battery. The energy is stored in chemical bonds between
Choose...
groups of the molecule, and the energy is released when the chemical bonds are broken.

Transposon can cause mutations in genes at or near the site of transposon insertion. it is possible for these elements to transpose away from their original site, causing a reversion of the mutant phenotype. in some cases, however, even more severe phenotypes appear when these elements excise from this site, 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?
