Difference between 70s and 80s ribosomes in hindi 1
Answers
Difference # 80S Ribosomes:
1. They occur only in eukaryotic cells.
2. They occur inside the cytoplasm of eukaryotes either freely or attached to ER.
The ribosomes are larger in size with a length of (300—340 A) and breadth (200—240 A).
4. The sedimentation co-efficient is 80.
5. They are comparatively heavier, 4.0—4.5 million Daltons.
6. The two subunits are 40S and 60S.Difference between 80S and 70S Ribosomes

9. 80S ribosomes are synthesized inside the nucleolus.
10. It contains about 73 protein molecules, 40 in larger subunit and 33 in smaller subunit.
11. Protein synthesis is not inhibited by common antibiotics like chloramphenicol.
Difference # 70S Ribosomes:

2. The ribosomes are found freely inside the cytoplasm of prokaryotes and matrix of plastids and mitochondria of eukaryotes.
3. They are comparatively smaller with a length of (200—290 A) and a diameter of (170— 210 A).
4. The sedimentation coefficient is 70.
