prokaryotic gene in a sentence

1. Introns are extremely rare in prokaryotes and therefore do not play a significant role in prokaryotic gene regulation.
2. The core promoter of prokaryotic genes, conversely, is sufficient for strong expression and is regulated by repressors.
3. The transcription of a basic prokaryotic gene is dependent on the strength of its promoter and the presence of activators or repressors.
4. Although all organisms use both transcriptional activators and repressors, eukaryotic genes are said to be'default off', whereas prokaryotic genes are'default on '.
5. Studies in evolution of eukaryotic genes and genomes involve the origin of exons, introns and splice junctions, as all eukaryotic genes are split into many exons separated by introns, whereas prokaryotic genes are not.
6. It's difficult to find prokaryotic gene in a sentence.
7. Sample contamination is an unlikely explanation for the unusual proteins because the recovered genes were always flanked by prokaryotic genes and no genes of known eukaryotic origin were detected in the metagenome from which the composite genome was extracted.
