The circular chromosome contains 1,830,137 bases and its publication in the journal Science [51] marked the first published use of whole-genome shotgun sequencing, eliminating the need for initial mapping efforts. By 2001, shotgun sequencing methods had been used to produce a draft sequence of the human genome. [52] [53]
While sequencing DNA gives a genetic profile of an organism, sequencing RNA reflects only the sequences that are actively expressed in the cells. To sequence RNA, the usual method is first to reverse transcribe the RNA extracted from the sample to generate cDNA fragments. This can then be sequenced as described above.
Whole genome sequencing (WGS) is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. [2] This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondria and, for plants, in the chloroplast.

The first genome to be sequenced was that of the virus φX174 in 1977; [4] the first genome sequence of a prokaryote (Haemophilus influenzae) was published in 1995; [5] the yeast (Saccharomyces cerevisiae) genome was the first eukaryotic genome to be sequenced in 1996. [6]
The answer is a process called DNA sequencing. Researchers sequence DNA to determine the order of the four chemical building blocks, or nucleotides, that make it up: adenine, thymine, cytosine and ...
Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing. Once ...
DNA sequencing is the process of determining the nucleotide sequence of a given DNA fragment. The sequence of the DNA of a living thing encodes the necessary information for that living thing to survive and reproduce. Therefore, determining the sequence is useful in fundamental research into why and how organisms live, as well as in applied ...
