Introduction
The long form of the periodic table is based upon the filling of a particular shell and has been accordingly divided into four blocks i.e. 's', 'p', 'd' and 'f' blocks. The 's' block elements involve the filling of 's' subshell. This block includes the elements of group 1 (or I A) and group 2 (or I..

Nucleic acids are giant macromolecules having a complex structure and very high molecular weight. They are polymers of nucleotides and hence, described as polynucleotides. There are two types of nucleic acids found in a cell, namely, deoxyribose nucleic acid (DNA) and ribose nucleic acid (RNA). In ..

At the molecular level all the different types of cells in living organisms are composed of certain chemical substances. The structure and function of the cell and its components are dependent on the molecular structure, arrangement and properties of these chemical constituents. The molecules found..
