Genome Projects are elucidating the complete genetic information or DNA sequence of an organism. This fundamental information will allow biologists and bio-medical researchers to understand the development of higher organisms and the biological foundations of diseases and infections.
Biologists place great hopes in genomics to better understand the history of life on Earth.
Two pieces of information warrant closer attention. First, the number of genes is estimated to be about 30,000 about one third of what has been expected over the last two decades. Most genome projects have deciphered the sequence of microbial and viral organisms. Among them are two strains of the coliform bacteria Escherichia coli . One of these E.coli is the cause of meat poisoning.
