Which of the following is found in eukaryotic but not prokaryotic genomes?

Question

Quizplus · Accepted Answer

Introns are found in eukaryotic genomes, but not prokaryotic genomes. This is because eukaryotic genes are typically interrupted by non-coding regions called introns, which must be spliced out before the mRNA is translated into protein. Prokaryotes lack introns, and their genes are typically contiguous (i.e. without interruptions).

The other answer choices are found in both eukaryotic and prokaryotic genomes. Promoters are regions of DNA that signal the start of a gene and are found in both types of genomes. Operons are clusters of genes that work together to produce a single mRNA molecule and are found in prokaryotic genomes. Genes are the basic unit of heredity and are found in both eukaryotic and prokaryotic genomes.
