WebBy Sugaprabha Prasath. A portion or a part in the genetic material that is the DNA or RNA that does not code for proteins, is called introns. Do eukaryotes have introns, … WebIn genes that lack introns (e.g. most prokaryotic genes), an ORF in the DNA sequence will define the entire translated region. If splicing occurs (i.e. in genes with introns), a final processed mRNA (transcript from a protein coding gene) will have a long ORF that directs ribosomes to produce a polypeptide. magnetism vocabularyWebAlmost all histone genes, for example, lack introns, so introns are clearly not required for gene function in eukaryotic cells. In addition, introns are not found in most genes of simple eukaryotes, such as yeasts. … magnetism third grade
