Differences in the genomes of prokaryotes and multicellular eukaryotes include the fact that eukaryotes have many more genes for metabolism and membrane transporters than prokaryotes do. the fact that eukaryotic DNA contains many non-coding and repeated sequences (both of which are rare in prokaryotes). the fact that the human genome is about 1000 times bigger than that of an E.coli bacterium.  the fact that prokaryotes have only one chromosome, while eukaryotic cells have many. Question 2    1 / 1 point Which of the following statements is/are correct about introns and exons? Exons can be alternatively spliced (i.e., different combinations of exons) to produce many different polypeptides from a  single gene. They are both sequences of DNA. Introns are part of the 'recipe' for a polypeptide. Exons must be snipped out by snRNPs as part of mRNA processing.
