WebThe reason that prokaryotic cells don't normally have introns in their genetic code is actually because of the mechanism of translation. In eukaryotic cells there is a thing … WebBacterial gene do not possess intron, their coding sequences are not interupted. … In higher eucaryotes there are often many introns within a gene, so one needs to specify what segments of a gene are coding and what are introns. However in bacteria introns are very rare and most genes have none. Do prokaryotes have introns?
WebDifferent cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and functional RNAs it contains, giving it its unique properties.
