It is impossible for RNA to store genetic information, because: a. RNA does not base pair and therefore cannot be replicated.
b. enzymes cannot process genetic information in the form of RNA.
c. RNA forms complex folded structures.
d. RNA is very unstable.
e. None of the above answers is correct; RNA can store genetic information.

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?
