Nucleotide is obtained by linking nucleoside to phosphoric acid at which position of sugar ?

The van't Hoff Factor, \(i\) for complete dissociation of (i) NaCl , (ii) \(MgSO _4\) and (iii) \(K _2 SO _4\) are

Answer the question on basis of passage given below :
P block elements are placed in groups 13 to 18 of the periodic table. Their valence shell electronic configuration is \(ns^2 np^{1-6}\). Group 16 of the p block elements are known as the group of chalcogens having \(ns^2 np^4\) as their general electronic configuration. They exhibit number of oxidation states but the stability of \(- 2\) oxidation state decreases down the group. They are sometimes also known as group of chalcogens as the name is derived from the Greek word for brass and points to the association of sulphur and its congeners with copper. Their ionisation enthalpy decreases down the group. Oxygen shows anomalous behaviour due to its small size and high electronegativity.
Given below are the Hydrides formed by group 15 elements. Choose the correct decreasing order of basicity of the following hydrides :
(A) \(AsH_3\)
(B) \(PH_3\)
(C) \(NH_3\)
(D) \(BiH_3\)
(E) \(SbH_3\)

Read the following passage carefully.
Restriction enzyme
Restriction enzymes cut the strand of DNA a little away from the center of the palindrome sites, but between the same two bases on the opposite strands. This leaves single stranded portions at the ends. There are overhanging stretches called sticky ends on each strand. These are named so because they form hydrogen bonds with their complementary cut counterparts. This stickiness of the ends facilitates the action of the enzyme DNA ligase. The word palindromes refer to group of letters that forms the same words when read both forward and backward. Restriction endonucleases are used in genetic engineering as molecular scissors.
Overhanging stretches on each strand is called:
