What is a genome map?

Every organism whether an animal, a plant, a fungus, a bacterium, an Archean, a protist or a virus, has DNA. A stretch of DNA that codes for a type of protein or for an RNA chain which has a function in the body / organism is called a Gene. So, a Gene is the basic unit of heredity. One the sequence of genes on DNA is identified; it can be scientifically manipulated for different purposes.
The aim of the genome projects is to determine the complete genome sequence of an organism.
In human there are 46 chromosomes, in 23 pairs. Out of them 22 pairs are called autosomes, while the 23rd pair is of sex chromosomes. To create a human genome map, a sequence of the genes on all the 46 chromosomes would be required. In bacteria, there is one Chromosome, (called genophore) so sequence of the genes on one Chromosome would create the genome map.
The process is complicated because it not only involves identifying elements on the genome (gene prediction) but also attaching biological information to these elements (gene annotation).
