It is the study of molecular organisation and mechanisms of organisms and their component..

Atoms of chemical elements combine with one another to form molecules. A molecule may have atoms of the same element (like O 2 , H 2 , N 2 ) or of different elements (like H 2 O, CO 2 , CH 4 etc..

Central Dogma of Molecular Biology - The expression of the genetic material occurs generally through the production of proteins. This involves 2 consecutive steps which are: Transcription Translati..

Molecular Basis of Differentiation - All the cells of an organism receive the complete set of genes (total information) present in the fertilized egg through mitotic divisions. However, cells of an early embryo lose the potential for the expression of all the genes through the processes o..

Development involves precisely coordinated series of events. Each gene is switched on in its turn, and then something resulting from the expression of that gene, or some environmental influence, switches on the next gene in the programm..

How does the neuroendocrine control work? The hormones are released in very small quantities, yet they can cause widespread dresponses in cells or tissues all over the body. These responses in cells or tissues all over the body. These responses can be quite specific and selective in different cell..

Nucleic acids are giant macromolecules having a complex structure and very high molecular weight. They are polymers of nucleotides and hence, described as polynucleotide..

The living cells contain specific macromolecules with a high molecular weight and a poor solubility. Generally in a cell, macromolecules are represented by polysaccharides, proteins, nucleic acids and enzymes. These compounds are formed by polymerisation of micromolecules such as sugars, ..

The macromolecules found in a cell are large molecules with a complex structure and very high molecular weight. They are represented by polysaccharides, proteins and nucleic acid..
