Introns and pseudogenes are not the same.

An intron is a segment of DNA that "intrudes" into or "interrupts" a coding stretch of DNA. Many genes in humans have introns, but bacteria seem to have none. To take an extreme example, the human dystrophin gene has 79 exons (separate coding segments) spread over more than 2.3 million base pairs.

A pseudogene is a DNA segment that resembles a functional (coding) gene, but does not itself code for a gene product. It seems likely that pseudogenes arise when a gene is copied within the genome, and one of the copies drifts away from the functional sequence. "Pseudogene" literally means "false gene".

How does pseudo genes contribute to evolutionary theory?

Pseudogenes are non-functional copies of genes that have accumulated mutations over time. By comparing pseudogenes across different species, scientists can study genetic changes that have occurred during evolution. Pseudogenes provide valuable insights into evolutionary processes and relationships between species.


Does mitochondrial DNA contain introns?

Yes, mitochondrial DNA does not contain introns. Mitochondrial DNA is a circular molecule that lacks introns, which are non-coding regions found in nuclear DNA.


Why are introns copied and then removed from the RNA sequence?

Introns were copied and then removed from the RNA sequence because they were placeholders.


Can prokaryotes remove introns during gene expression?

No, prokaryotes do not remove introns during gene expression.
