Does the presence of introns/exons in eukaryotic cells provide more potential diversity in gene products (proteins) than is possible in prokaryotic cells?
A. It doesn't-this is a trick question. There's the same potential for gene products (proteins) in a bacterium with 1,000 genes as there is in a eukaryotic cell with 1,000 genes. B. It does-each exon and each intron could be used individually and discretely to make agene product (protein). Since bacteria lack these, they will have less ability to create different proteins. C. It does-exons/introns can be spliced together in different ways post-transcription to yield different mRNAs (and therefore, different proteins). Bacteria lack this system, so the gene you transcribe is translated into the only protein you'll end up getting. D. It does-exons/introns can be spliced together in different ways at the DNA levelto eventually yield different mRNAs (and therefore, different proteins). Bacteria lack this system, so the gene you transcribe is translated into the only protein you'll end up getting.
