DNA molecule is a double helical structure made of deoxyribo nucleotides. RNA is also present in nucleus as well as cytoplasm. DNA is the major source of genetic information which is copied into RNA molecules (transcription). The sequence of nucleotides contains the 'code' for specific a..

Ionization isomerism - Compounds, which give different ions in solution although they have same composition are called ionization isomers. There is an exchange in groups between the coordination sphere of the metal ion and ions outside the sphere. Exampl..

Structure of Cell - Cells vary in shape and size. They may be oval, spherical, rectangular, polygonal, spindle shaped, star shaped, rod-shaped or totally irregular like the nerve cell. The diversity in cells is in accordance with the role or function it has to perform as part of the tissu..

Structure of the Earth - During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a distinct distribution ..

Structurally all types of chlorophyll resemble one another. All of them contain four pyrrole rings [also called porphyrin] which are linked together by methane bridges (-CH=). The skeleton of each pyrrole ring is made up of five atoms - four carbon and one nitrogen with magnesium in the c..
