The type of antibodies that produce the immune response in the presence of allergens like pollen, dust, animal dander etc. is _________

Read the following passage carefully and answer the given questions
The separated DNA fragments can be visualized only after staining the DNA with ethidium bromide followed by exposure to UV radiation. Bright orange colored bands of DNA in ethidium bromide stained gel exposed to UV light can be seen. The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution. The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with a cloning vector.
Which one of the following techniques is used to separate DNA fragments?

Match List - I with List - II.

List I (Name)	List - II (Functions)
(A) mRNA	(I) amino acid carrier
(B) rRNA	(II) structural and catalytic role during translation
(C) tRNA	(IV) template for protein synthesis
(D) cistron	(III) gene

Which of the following statements are correct about the "Central Limit Theorem"?
(A) The sampling distribution of the sample mean approaches the normal distribution as the sample size gets larger.
(B) A sample size of 30 or more is considered to be sufficient to hold the "Central Limit Theorem".
(C) As the sample size becomes larger, the prediction of characteristics of the population becomes more accurate.
(D) The sampling distribution of the sample mean approaches bell shaped curveas the sample size gets larger.
