Description :
The first truly efficient technique to sequence DNA was discovered in 1977. In 1995, the first sequence of an entire genome (from the microbe Hemophilus influenzae) was determined. Between these two dates, DNA sequencing technologies improved steadily, but such technologies still tended to concentrate on mining individual genes for information. During this period, biologists were mostly sequencing DNA fragments that were a few thousand nucleotides in length, simply because they were interested in specific genes that they had started working on years before. Most of the bioinformatics tools available today were created during that period
