DNA-Based Molecular Markers in Biotechnology

The techniques of cloning and PCR amplification of small DNA fragments to obtain millions of copies of each such fragment.

These techniques are now extensively used for a variety of purposes in the broad area of biotechnology.

One of the major uses of these tools is the development and use of DNA-based molecular markers for a variety of purposes.

These molecular markers are based on the polymorphism detected at the level of small DNA fragments.

During a period of two decades spanning over 1980 to 2000, a broad range of molecular markers became available, which are being used in a variety of ways.

A large number of acronyms for these molecular markers are in common usage now.

The major uses of these molecular markers is the development of molecular maps, that will be described in for humans and animal systems and for a variety of plant systems.

Only the basic principles and methods involved in the development and uses of these molecular markers will be discussed, since they are common to all kinds of organisms.
