Automated DNA sequencing output

The output from an automated DNA sequencing robot used by the Human Genome Project to determine the complete human DNA sequence. Each peak shows the presence of a particular base. The sequence of bases in a given stretch of DNA can therefore be read from the order of the peaks along the trace. The sequences of different overlapping traces are ordered by the computer and assembled to give the continuous base sequence of each chromosome.
