Gene sequence codes looks for the amino acids that formproteins within the DNA strand. Sequencing involves determining the order ofthe protein bases. The common chemical units are represented by the letters A,C, G and T, in the stretch of a DNA strand. The more difficult challengewill be to decipher what all the chemical units represented by those letters inthe human genome sequence mean. Ingeneral, each gene codes for the production of a single protein, and a gene andits protein can be related to each other by means of the genetic code.

Therefore, scientists will be able to turn to the DNA sequence of the humangenome and obtain detailed information on both the structure and function ofany gene or protein of interest. In addition, all genes and proteins will beclassified into large family groups that provide valuable clues to their functions. One major concern is over privacy and security ofgenomic data. Complicating the privacy issue is the fact that there’s noclear legal owner of genomic data; that data was found to be unpatentable and,because it lacks authorship or a creator (legally), cannot be copyrighted.
