Prokaryotes (bacteria and archae) have cytoskeletons which are homologous of eukaryotic cytoskeleton components (like actin and microtubules). What is the cytoskeleton important for? |
Cell division Positioning of cytoplasmic components Cell shape |
|
|
Ribosomes create proteins in the cell. How are prokaryotic ribosomes different from eukaryotic ribosomes? |
Bacterial ribosomes: - made of protein and rRNA - 70S ribosomes = smaller than eukaryotic ribosomes (Eukaryotes have 80S) - slightly different structure - perform same exact functio - have 2 subunits (small subunit and large subunit) |
|

What does the S stand for in 70S, 80S, etc? What does it measure? |
S stands for Svedberg and is a unit that measures size, not weight. |
