Question

Prokaryotic and eukaryotic RNA's differ in that:

		ribosomal subunits have different percentages of rRNA to protein
		Eukaryotes have a pre-mRNA that requires splicing to create the functional transcript
		Prokaryotes have non-coding sequences that are removed during RNA-transcript processing
		Eukaryotes have ribosomes consisting of only one subunit.

Answer 1

1. In eukaryotes, ribosomes are roughly 40 percent protein and 60 percent rRNA. Whereas in prokaryotes,  30 percent protein and 50  percent rRNA is present.

2 . Eukaryotic mRNA have introns (non coding sequence) and exons (coding sequence) parts . In splicing, introns are removes and exons are joined before translation.

But prokaryotic mRNA ave only exon part so do not need RNA splicing before Translation.
