Question

Quizplus · Accepted Answer

Introns are found in eukaryotic genes but not prokaryotic genes. Introns are non-coding DNA sequences that are transcribed into mRNA but are removed by RNA splicing before the final mRNA is produced. Prokaryotic genes do not have introns, as their transcription and translation processes are more tightly coupled than in eukaryotes. Repressors and operons, on the other hand, are found in both prokaryotic and eukaryotic genes.
