The cell membranes are mainly composed of:

1. Phospholipids

2. Proteins

3. Fats

4. Carbohydrates

Telomerase is an enzyme that is a:

1. RNA

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:
 

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:

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
