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
The genetic material of prokaryotic cell:
| 1. | Non histonic double-stranded DNA |
| 2. | Histonic double-stranded DNA |
| 3. | Histone & DNA both are absent |
| 4. | Histone without DNA |
Which cell organelle is concerned with the glycosylation of protein:
1. Ribosome
2. Peroxisome
3. Endoplasmic reticulum
4. Mitochondria
The function of telomeres in the nucleus:
| 1. | Pole ward movement |
| 2. | To initiate the RNA synthesis |
| 3. | To seal the ends of chromosome |
| 4. | To recognize the homologous chromosome |
In the fluid mosaic model of a plasma membrane:
| 1. | Upper layer is non-polar and hydrophilic |
| 2. | The polar layer is hydrophobic |
| 3. | Phospholipids form a bimolecular layer in the middle part |
| 4. | Proteins form a middle layer |
