"DNA- Decoding the Genomes"
By : Paolo Manzelli <LRE-UNIFI.IT>
The Genetic Heritage of all living creatures is controlled by a big molecule called
DNA ( desoxy Ribo Nucleic Acid . The DNA is generally structured as well as a double
helix and it is the organized by a series of Chromosomes.
The DNA carries the genetic information needed for the synthesis af all "Proteins", which are chemical building blocks of living creature creation.
Each protein is coded by a "Gene (e.g. a single piece of DNA) Each Gene is
composed thought a long sequence of four nucleotides Bases that are the
chemical letters of the genetic information.
As a matter of facts this nucleotide sequence is the structural basis of the entire
DNA that is subdivided in a large quantity of sections called Genes.
Till now Bio- Sciences di not know the real meaning of the different composition
of the "chemical alphabet" that gives the genetic information for expressing the
living organization of proteins of each living creature. So that Bio-Sciences
nowadays is limited to decode the Nucleotide letters aiming to understand their
hidden meaning. Recently Bio-Science is very advanced in the knowledge of the
structural composition of DNA double helix and its sequencing in Genes.Chips:
The Complete sequencing of the Human Genome was recently discovered and it
is composed by three billions of "nucleotide letters" .
The study of the sequencing of a complete Genome of each living species. Id named "Genomics" while the decoding studies of each single gene is called "Genetics".
Genomics is closely correlated with "Proteomics" , the last is concerned with the
studies of the complete expression of proteins produced in a living organism.
