reference map of the
human genome.

Humans vary in their DNA
sequences, and what is taken as the «normal» DNA

sequenced the DNA, mapping it against a
human reference genome.
Yet, «these studies using HeLa cells had to rely on information from the «
reference»
sequence produced by the
Human Genome Project, even though there was evidence that the genomes of HeLa cell lines were probably quite different,» said Lars Steinmetz, Ph.D., who led the G3 study.
Using the new approach in the hydatidiform genome, the researchers were able to identify and

For the Standard
Sequencing Service, all of these variation types are identified in comparison to the
human genome
reference.
While these variants are all determined in comparison to the
human genome
reference, genomes submitted for the Cancer
Sequencing Service are additionally analyzed for somatic variants called in comparison to the baseline genome within the submitted pair or trio.
We have a variety of data, both from actual assemblies and simulation studies, which show that about 96 % of the
reference human genome is addressable using this library and
sequencing strategy, including a significant fraction of the high - copy repeat
sequences in the genome.
The data include
sequence reads, their mappings to a
reference human genome, and variations detected against the
reference human genome.

human sequence known as the
reference sequence (Anderson et al. 1981) was 22, compared to 27 for the first Neandertal.
Note that (in
reference to Krings et al. 2007) because two modern
human sequences are 24 bases apart, while the smallest Neandertal /
human difference is only 22, this does not mean that the Neandertal
sequence is within the range of modern
humans.
