Gene Sequencing | DNA molecules

Gene sequencing is a method of determining nucleotide sequence of a gene (DNA molecules). This gene sequence can provide great deal of information. It is fastest way to determine amino acid sequence of its polypeptide. It provides location of restriction site with in a gene which can be manipulated further later on. Man's phases of gene friquencing are firstly to cut genes into specific small pieces, then each fragment is individually sequenced. Most sequences, that are determined are being collected in computer data bank that are valuable for biotechnology with the help of computers long sequences can be scanned for shorter segments known to be control sequences such as promotes or enhances. It is also possible to scan a DNA sample to know sequences in other genes or organisms.
