View Answer
Answer: (c)
RNAi is a method of cellular defense in all eukaryotes. It is a system within living cells that helps to control the activity of specific genes. This method involves silencing of mRNA due to complementary double stranded RNA that prevents translation of target gene or mRNA[silencing]. Source of ds RNA is retrovirus (having RNA genome) or transposons (mobile genetic material).
Question : 10

Question : 11
Assertion (A) ADA deficiency disorder is caused due to the excessive synthesis of gene for adenosine deaminase.
Reason (R)It affects the human immune system.
View Answer
Answer: (d)
Assertion is false, but Reason is true. Assertion can be corrected as
ADA deficiency disorder is caused due to the lack of gene which codes for adenosine deaminase. This enzyme is crucial for the immune system to function. Thus, ADA deficiency affects the immune system of the human.
Question : 12
Match the following columns and select the correct option.
| Column I | Column II |
| (A) Bt cotton | (i) Diptera |
| (B) Adenosine deaminase deficiency | (ii) Cellular defence |
| (C) RNAi | (iii) Detection of HIV infection |
| (D) PCR | (iv) Bacillus thuringiensis |
View Answer
Answer: (c)
Question : 13
cry IIAb and cry IAb produce toxins that control
View Answer
Answer: (b)
Bt toxin genes are isolated from Bacillus thuringiensis and incorporated into several crop plants such as cotton. The toxin is coded by a gene named cry. The proteins encoded by the gene cry II Ab and cry I Ac control the cotton bollworms and that of cry I Ab have corn borers.
Question : 15
Assertion:
A functional ADA c DNA is introduced in lymphocyte using retroviral vector.
Reason:
Disarmed retrovirus is use to deliver gene in animal cells.
