How many genes do prokaryotes have
WebProkaryotes have only three ribosomal RNAs ( 23S, 16S, and 5S), which are similar to the 28S, 18S, and 5S rRNAs found in eukaryotic cells and are generated from the same pre-rRNA transcript. This also shows that they are similar in function. Do prokaryotes have RNA splicing? Prokaryotes essentially do not require to perform splicing.
