Extranuclear DNA is found in:
1. Lysosome and chloroplast
2. Chloroplast and mitochondria
3. Mitochondria and lysosome
4. Golgi and E.R.
Extranuclear chromosomes occur in:
1. | Peroxisome and ribosome | 2. | Chloroplast and mitochondria |
3. | Mitochondria and ribosome | 4. | Chloroplast and lysosome |
Extranuclear inheritance is a consequence of the presence of genes in:
1. Endoplasmic reticulum & mitochondria
2. Ribosomes and chloroplasts
3. Lysosomes and ribosomes
4. Mitochondria and chloroplasts
Select the wrong statement from the following:
1. | Both chloroplast and mitochondria contain an inner and an outer membrane |
2. | Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane |
3. | Both chloroplasts and mitochondria contain DNA |
4. | The chloroplasts are generally much larger than mitochondria |
Which one of the following has its own DNA?
1. Mitochondria
2. Dictyosome
3. Lysosome
4. Peroxisome
The figure below shows the structure of a mitochondrion with its four parts labelled (A), (B), (C) and (D). Select the part correctly matched with its function.
1. | Part (A) : Matrix – a major site for respiratory chain enzymes |
2. | Part (D) : Outer membrane – gives rise to the inner membrane by splitting |
3. | Part (B) : Inner membrane – forms infoldings called cristae |
4. | Part (C) : Cristae – possess single circular DNA molecule and ribosome |
