Genome

A genome is one which is entirety of an organism's hereditary information.
The genome includes both the genes and the non-coding sequences of the DNA.It can be defined as the ordering of genes in a haploid set of chromosomes of a particular organism; the full DNA sequence of an organism.It is the complete genetic material of a living thing.
Humans and many other higher animals actually have two genomes, which together make up the total genome:
1) A chromosomal genome -- inside the nucleus of the cell in the familiar form of chromosomes.
2) A mitochondrial genome -- outside the nucleus in the cytoplasm of the cell,usually in the form of one round chromosome (the mitochondrial chromosome)
Full genome sequencing is a laboratory process that determines the complete DNA sequence of an organism's genome at a single time.Full genome sequencing would have been nearly impossible before the advent of the microprocessor, computers, and the Information Age.Full genome sequencing should not be confused with DNA profiling.
