#Unit 2. Cellular Organization

Introns have negative Fold Potential i.e. potential to form stem loop.

#Id: 466

#Unit 2. Cellular Organization

Overlapping gene are the same sequence of DNA encodes two nonhomologous proteins because it uses more than one reading frame.

#Id: 467

#Unit 2. Cellular Organization

Mutations occur at the same rate in both exons and introns, but exon mutations are eliminated more effectively by selection.

#Id: 468

#Unit 2. Cellular Organization

Introns may more freely accumulate point substitutions and other changes due to no selection pressure.

#Id: 469

#Unit 2. Cellular Organization

Introns evolve or accumulate mutations/changes much more rapidly than exons

#Id: 470

#Unit 2. Cellular Organization

Intron do not face selective pressure to produce a polypeptide with a useful sequence hence highly variable.
