All in all, the virus - like
components of the human genome amount to almost half of our DNA.
As a result of this large - scale, global collaboration between 440 researchers in 32 labs, 80 % of
components of the human genome are now associated with at least one biochemical function.

To determine how the cells switch from one type to another, they took three
human uterine carcinosarcoma samples and sequenced the
genomes of cells in two parts
of each tumor: the carcinoma and sarcoma
components.
The mitochondrial
genome of healthy
humans also exhibits some natural variation — a single
component of the mitochondrial DNA sometimes differs between one
human and another — this is known as a SNP (single nucleotide polymorphism, «snip»).
The properties
of the
human Y chromosome - namely, male specificity, haploidy and escape from crossing over - make it an unusual
component of the
genome, and have led to its genetic variation becoming a key part
of studies
of human evolution, population history, genealogy, forensics and male medical genetics.
