Introns are placed at the boundaries between protein domains. They tend to occur in the same regions but the lengths of introns may vary. WebPoint 3: prok genes are polycistronic (cistron, ORF)-cistron: structural gene-ORF: open reading frame- any sequence of DNA or RNA that could (in theory) encode a protein without interrupted by stop codon prematurely.

The words cistron and gene were coined before the advancing state of biology made it clear that the concepts they refer to are practically equivalent. The same historical naming practices are responsible for many of the synonyms in the life sciences. The term cistron was coined by Seymour Benzer in an article entitled … See more A cistron is an alternative term for "gene". The word cistron is used to emphasize that genes exhibit a specific behavior in a cis-trans test; distinct positions (or loci) within a genome are cistronic.
