The main organelle involved in the modification and routing of newly synthesized proteins to their destinations is -
1. Endoplasmic Reticulum
2. Lysosome
3. Mitochondria
4. Chloroplast
Chlorophyll in chloroplasts is located in:
1. Grana
2. Pyrenoid
3. Stroma
4. Both (1) and (3)
Role of microtubules is:
| 1. | To help in cell division |
| 2. | Cell membrane formation |
| 3. | Respiration |
| 4. | Pinocytosis |
Difference between eukaryotes and prokaryotes is in:
| 1. | Circular ss DNA in prokaryotes |
| 2. | Histone with prokaryotic DNA |
| 3. | Operon in eukaryotes |
| 4. | Membrane bound organelles in eukaryotes |
Flagella of prokaryotic and eukaryotic cells differ in:
| 1. | Location in cell and mode of functioning |
| 2. | Microtubular organization and type of movement |
| 3. | Microtubular organization and function |
| 4. | Type of movement & placement in the cell |
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 |
In chloroplasts, chlorophyll is present in the:
1. Inner membrane
2. Thylakoids
3. Stroma
4. Outer membrane
Plant pathogenic bacteria are mostly:
| 1. | Gram + Non-spore forming |
| 2. | Gram – Non-spore forming |
| 3. | Gram + spore forming |
| 4. | Gram (–) spore forming |
The telomeres of eukaryotic chromosomes consist of short sequences of:
1. Cytosine-rich repeats
2. Adenine-rich repeats
3. Guanine-rich repeats
4. Thymine-rich repeats
Double unit membrane is absent in:
1. Ribosomes
2. Nucleus
3. Plastids
4. E.R
