#Unit 2. Cellular Organization

Introns are nucleotide sequence which cannot encode functional proteins or polypeptides or introns do not have a sequence-specific function.

#Unit 2. Cellular Organization

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

#Unit 2. Cellular Organization

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

#Unit 2. Cellular Organization

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

#Unit 2. Cellular Organization

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

#Unit 2. Cellular Organization

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