Early Foundations

The word genome enters English usage

1926

The word genome, derived from the German 'Genom' attributed to Hans Winkler, was already in use in English by 1926, laying the terminological groundwork for the future science of genomics.

Sequencing Milestones

First gene sequence determined by Walter Fiers

Sequencing Technologies

Sanger and Coulson publish the Plus and Minus technique

1975

In 1975, Fred Sanger and Alan Coulson published a sequencing procedure using DNA polymerase with radiolabelled nucleotides, which Sanger called the Plus and Minus technique, an important early method for reading DNA sequences.

Refinement of chain-termination (Sanger) sequencing method

1977

The refinement of the Plus and Minus method resulted in the chain-termination, or Sanger method, which formed the basis of the techniques of DNA sequencing, genome mapping, data storage, and bioinformatic analysis most widely used over the following quarter-century of research.

Shotgun sequencing enables long DNA sequence analysis

1980

Shotgun sequencing is a method designed for analyzing DNA sequences longer than 1000 base pairs, up to and including entire chromosomes. Longer DNA is broken into random small segments which are then individually sequenced and reassembled computationally into contiguous reads.

Shotgun sequencing enables long DNA sequence analysis

Gel electrophoresis limits sequencing to short reads

1980

Because gel electrophoresis sequencing can only be used for fairly short sequences of roughly 100 to 1000 base pairs, longer DNA molecules must be broken into smaller random segments before they can be sequenced and reconstructed, motivating methods like shotgun sequencing.

Illumina dye sequencing method developed

1996

The Illumina dye sequencing method, based on reversible dye-terminators, was developed in 1996 at the Geneva Biomedical Research Institute by Pascal Mayer and Laurent Farinelli, later becoming one of the most dominant high-throughput sequencing technologies in genomics.

Modern sequencing technology limited to short fragment reads

2010

Current DNA sequencing technology cannot read whole genomes as continuous sequences; instead it produces short pieces of between 20 and 1000 bases depending on the technology used, requiring computational assembly to reconstruct full genomes.
