Differences between prokaryotes/eukaryotes The prokaryotic cell, in contrast to the eukaryotic cell, has no nuclear membranes, mitochondria, endoplasmic reticulum, golgi body, phagosomes and lysosomes Prokaryotes generally possess only a single circular chromosome Since there is no nuclear membrane the chromosome is bound to a specific site on the cell membrane- the mesosome Prokaryotic ribosomes are 70S(S means Svedberg unit, a measure of size for centrifugation), whereas eukaryotic ribosomes are larger (80S) Prokaryotic ribosomal subunits are 30S and 50s (eukaryotic are larger). The 30S ribosome has 16S RNA, while the 50S ribosome contains 23S and 5S rna• The prokaryotic cell, in contrast to the eukaryotic cell, has no nuclear membranes, mitochondria, endoplasmic reticulum, Golgi body, phagosomes and lysosomes. Differences between prokaryotes/eukaryotes • Prokaryotes generally possess only a single circular chromosome. Since there is no nuclear membrane, the chromosome is bound to a specific site on the cell membrane - the mesosome. • Prokaryotic ribosomes are 70S (S means Svedberg unit, a measure of size for centrifugation), whereas eukaryotic ribosomes are larger (80S). •Prokaryotic ribosomal subunits are 30S and 50S (eukaryotic are larger). The 30S ribosome has 16S RNA, while the 50S ribosome contains 23S and 5S RNA
