DNA sequencing

noun

1. the procedure of determining the order of base pairs in a section of DNA

DNA sequencing

1. The determination of the sequence of nucleotides in a sample of DNA.

DNA sequencing

1. A process by which the sequence of nucleotides along a strand of DNA is determined. Originally a difficult process to carry out, DNA sequencing can now be done routinely by machines. The completion of the Human Genome Project in 2000 produced the largest DNA sequence ever assembled. To carry out the sequencing of the human genome, scientists cut the DNA up into short fragments, sequenced these fragments simultaneously, and then assembled the entire genome by using sophisticated computer techniques to match the fragments to each other.

Notes

Many believe that knowledge of the human genome will lead to enormous advances in medicine. ( Compare gene mapping and DNA fingerprinting .)

Example Sentences

Federal officials also noted that DNA sequencing of virus obtained from one of the patients is closely related both to infected chickens from that farm, as well as to the first dairy worker infected in Texas in April and to infected dairy herds located near the Colorado poultry farm.

From Los Angeles Times

The researchers further investigated eight of the samples via 3D-guided microdissection and DNA sequencing of specific PanINs.

From Science Daily

The discovery was enabled by a single-cell sequencing technology called Strand-seq, a unique DNA sequencing technique that can reveal subtle details of genomes in single cells that are too difficult to detect with other methods.

From Science Daily

Now, after a heroic DNA sequencing effort, a collaboration involving hundreds of scientists has created a new family tree for flowering plants.

From New York Times

From their new reference genome, accomplished using cutting-edge DNA sequencing technology and advanced data science, the team was able to sequence 39 Arabica varieties and even an 18th century specimen used by Swedish naturalist Carl Linnaeus to name the species.
