70S ribosome breaks up into two subunits whose sedimentation constants are
1 50s and 30s
2 80s and 50s
3 50s and 20s
4 40s and 30s
Explanation:
The sedimentation constant of ribosomes is 70s; it breaks up into two subunits whose sedimentation constants are 50s and 30s which when present together form 70s prokaryotic ribosomes.

Assertion : Ribosomes are non-membrane bound organelles found in the prokaryotic cells only. Reason : These are present only in the cytoplasm
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false
Explanation:
Ribosomes are non-membrane bound organelles found in eukaryotic and prokaryotic cells, within a cell. Ribosomes are found not only in the cytoplasm but also within two organelles chloroplasts (in plants) and mitochondria and on rough endoplasmic reticulum.

Which one of the following structure is an organelle within an organelle?
1 Mesosome
2 Ribosome
3 Peroxisome
4 Endoplasmic reticulum
Explanation:
The ribosomes are the cell organelle that is present inside the other cell organelles like endoplas-mic reticulum, mitochondria, and chloroplast. So we can call it as an organelle within an organelle.
