Each ribosome consists of 2 subunits called large and smaller subunits. The association and dissociation of subunits of ribosomes depend on Mg ion concentration.
Mitochondria and chloroplasts can grow and divide to reproduce themselves due to the presence of its own DNA and partially depend on other cellular components. So, called as semi-autonomous organelles.
During cell division, nuclear envelope disappears in prophase and reappears in telophase stage.
Cytochrome P-450 is present in mitochondria and endoplasmic reticulum and absent in Golgi. It is an important protein which involved in the metabolism. Thus, the correct answer is option B.

Which one of the following statements is not correct?a)The magnesium f...
Magnesium in Ribosome Units
- Ribosomes are cellular structures responsible for protein synthesis.
- They consist of two subunits, the large subunit and the small subunit.
- The small subunit contains a small amount of magnesium ions, which are important for stabilizing the structure of the ribosome and facilitating protein synthesis.
Semi-Autonomous Chloroplasts
- Chloroplasts are organelles found in plant cells that are responsible for photosynthesis.
- They are believed to have originated from free-living photosynthetic bacteria that were engulfed by ancestral eukaryotic cells.
- Chloroplasts have their own DNA and can synthesize some of their own proteins.
- They are considered semi-autonomous organelles because they are able to replicate and divide independently of the cell.
Cytochrome P-450 in Golgi Complex
- Cytochrome P-450 is a family of enzymes that play a crucial role in the metabolism of a wide range of compounds.
- These enzymes are primarily found in the endoplasmic reticulum, not the Golgi complex.
- The endoplasmic reticulum is involved in protein synthesis and lipid metabolism, and it is the main site of production for cytochrome P-450 enzymes.
Nuclear Envelope in Telophase Stage
- Telophase is the final stage of mitosis, the process by which cells divide.
- During telophase, the nuclear envelope, which had broken down during prophase, reforms around the two sets of daughter chromosomes.
- This reformation of the nuclear envelope marks the end of mitosis and the formation of two separate nuclei in the daughter cells.
Conclusion:
- Based on the explanations above, the statement that is not correct is option C, "Cytochrome P-450 found in Golgi complex".
- Cytochrome P-450 enzymes are primarily found in the endoplasmic reticulum, not the Golgi complex.
