Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
BARSIC [14]
Answer: B

WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

Answer:

The bacterium Vibrio cholerae is the primary cause of cholera disease that mainly infects the small intestine and primarily leads to the dehydration of the body.

Explanation:

The genetic analysis reveals that the aforementioned causative bacteria surpass the acidic conditions of the stomach and eventually reaches the intestinal wall and attaches to it. This is followed by the production of toxic protein by the bacterium. This protein is taken inside the cell via receptor mediated endocytosis followed by its binding to the host protein Arf6. This binding leads to the production of cAMP that results in the dehydration process. This mechanism leads to excessive accumulation of chloride ion in the intestine preventing the entry of sodium ion.

These two ions are associated with the creation of water-salt environment in the intestine that leads to tremendous diarrhea via the process of osmosis.

Hence, we can say that cholera bacterium affects the individuals at the cellular level and osmosis plays a vital role in the process.
