Molecular marker's

MOLECULAR MARKER= BIOSIGNATUR= BIOMARKER= GENETIC MARKER= DETECTOR MARKER

Marker is a piece of DNA molecule associated with a certain traits of an organism. Molecular marker is use to monitor DNA sequence variations among the species, create new favorable traits to related species. Molecular marker consists of molecules which show easily detectable differences among different strains of a species or among different species. Thus “A DNA sequence on the genome which can be located and identified” is known as Molecular Marker.

In recent years the use of molecular marker approaches for plant breeding where use to

1.      Study variety of transgenic crops for gene they contains

2.      Study link to numerous traits of economic importance.

 Molecular markers reveals neutral sites of variation at the DNA sequence levels known as “Neutral Sites”

A map of the location of identifiable landmark on chromosome is known as “Genetic Map”  and a gene or DNA sequence having a known location on a chromosome and associated with a particular trait or gene is known as “Genetic Marker”.
