One difference between eukaryotic and prokaryotic cells is that eukaryotic cells prokaryotic cells. (a) have a nucleoid region, which is lacking in. (b) lack the complexity seen in. (c) have membrane-bound organelles, which are lacking in. (d) have dna, which is lacking in. (e) have a plasma membrane, which is lacking in.

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?
