Q. No.Given below are two statements:
Statement I:
Bacillus thuringiensis forms protein crystals which contain a toxin that kills certain insects but not Bacillus because Bt toxin protein exists as inactive protoxins in Bacillus.
Statement II:
Bacillus thuringiensis forms protein crystals which contain a toxin that kills certain insects but not Bacillus because toxin requires alkaline pH available in the gut of insects and which solubilises the crystals in order to convert into an active form.
In light of the above statements, choose the most appropriate answer from the options given below.
1. Both statement I and statement II are true
2. Both statement I and statement II are false
3. Statement I is correct but statement II is false
4. Statement I is incorrect but statement II is true

Mutations in the CFTR gene cause cystic fibrosis (CF). The non-mutated allele of the gene can be obtained and then introduced into the lung cells of a person with CF using liposomes as a vector. This treatment gives only short-term relief from the symptoms of CF.
Which of the following statements would be a correct explanation of this treatment?
1. (i) and (ii) only
2. (i) only
3. (ii) only
4. (i) and (iii) only
Which of the following statements would be a correct explanation of this treatment?
| (i) | Genes are unstable and break down over time in the cell. |
| (ii) | Lung cells are constantly being replaced and new cells will have the faulty allele. |
| (iii) | The non-mutated allele is recessive. |
