The component of the 30S small subunit of a prokaryotic ribosome that binds to the Shine-Dalgarno sequence is:
1. 5 S
2. 16 S
3. 23 S
4. 28 s

Consider the given two statements:
I. Even though mitochondria possess ribosomes similar to the bacterial ones, mitochondria are not affected by the antibiotics that affect bacteria
II. Oxygen in mitochondria inactivates these antibiotic molecules

1. Both I and II are correct and II explains I
2. Both I and are correct but II does not explain I
3. I is correct and II is incorrect
4. Both I and II are incorrect

Cholera causes rapid severe dehydration and often leads to death. Oral rehydration therapy, feeding dilute salts and glucose is very effective because:
1. bacterial damage to intestinal transport of ions is reversed by glucose
2. the active transport of glucose and sodium from the cell to the intestine is still intact
3. the secondary active transport or co-transport systems of the intestine are still functioning
4. the dilute salts and glucose cause removal of excess water from the body

The given diagram shows the structure of:

1. Flagellum in Gram negative bacteria
2. Flagellum in Gram positive bacteria
3. Eukaryotic flagellum
4. Pili in prokaryotes

In which of the following bacterial cells will the flagellar insertion be termed as lophotrichous ?

1. 

2. 

3. 

4. 

Consider the given two statements:
I. In plants the glyoxylate cycle occurs in special peroxisomes which are called glyoxysomes.
II. This cycle allows seeds to use lipids as a source of energy to form the shoot during germination.
1. Both I and II are correct and II explains I
2. Both I and are correct but II does not explain I
3. I is correct and II is incorrect
4. Both I and II are incorrect

Identify the incorrect statement regarding endospores in bacteria:
1. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria and archaea.
2. Endospore formation is usually triggered by a lack of nutrients, and usually occurs in gram-positive bacteria.
3. The endospore consists of the bacterium's DNA, ribosomes and large amounts of dipicolinic acid.
4. When favorable conditions return, a large number of cells are produced as a result of endospore germination.

Consider the given two statements

I. Placing phospholipids into an aqueous solution immediately results in their forming a lipid bilayer.
II. Phospholipids have a strong affinity for other phospholipids, leading to self assembly by covalent bonding.

1. Both I and II are correct and II explains I
2. Both I and are correct but II does not explain I
3. I is correct and II is incorrect
4. Both I and II are incorrect

Consider the given two statements:

II. The cell wall is the only deciding factor for many bacterial cell shapes.

1. Both I and II are correct and II explains I
2. Both I and are correct but II does not explain I
3. I is correct and II is incorrect
4. Both I and II are incorrect

Cytoskeleton elements involved in muscle contraction, cytokinesis and cytoplasmic streaming are:
1. Microfilaments
2. Intermediate filaments
3. Microtubules
4. FTS-Z
