2. Ribonucleoprotein
3. Repetitive DNA
4. Simple protein

According to the widely accepted "fluid mosaic model", cell membranes are semi-fluid, where lipids and integral proteins can diffuse randomly. In recent years, this model has been modified in several respects. In this regard, which of the following statements is incorrect:
| 1. | Proteins can also undergo flip-flop movements in the lipid bilayer |
| 2. | Many proteins remain completely embedded within the lipid bilayer |
| 3. | Proteins in cell membranes can travel within the lipid bilayer |
| 4. | Proteins can remain confined within certain domains of the membrane |
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
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 |
