Introduction
The molecular basis of pattern of inheritance as explained by Gregor Mendel will be explained in this tutorial.
The living cells and organisms are characterized by their
- ability to reproduce
- transmit characteristics, generations after generations
- maintain continuity of inherited traits.
In twentieth century, one of the land mark discovery in biology was the identification of DNA. as a genetic material of living organisms.
The continued existence of a biological species requires its genetic material:
- chemically stable
- Express accurately
- capacity to replicate with minimum errors.
- provides the scope for changes (mutation) that are required for evolution
The miraculous organic compound DNA shows all these features.
