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

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
