Tests
Confirms active hepatitis C infection and verifies cure after treatment.
Glossary Term
Having two different allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.

Glossary Term
Placeholder definition before migration.
Glossary Term
Major protein component of chromatin. Highly conserved basic proteins, originally classified into classes based on the relative amounts of arginine and lysine in each protein. The various classes are now termed H1, H2A, H2B, H3, and H4. In chromatin, they are found in an octamer, containing two each of H2A, H2B, H3, and H4, complexed with DNA in nucleosomes. The histones in the octamer complex are also known as the core histones. The H1 class of histones, termed the linker histones, is loosely associated with the nucleosome.
Tests
An HIV viral load test measures the amount of HIV in a sample of your blood. HIV stands for human immunodeficiency virus. The test looks for genetic material from the virus in your blood. These tests are called molecular tests or nucleic acid amplification tests (NAAT or NAT). There are several types of NAAT tests. A PCR test is one type of NAAT that may be used to find HIV.
Tests
The determination of the HIV viral load in a specimen using polymerase chain reaction.
Tests
Quantitative measurement of HIV-1 RNA to stage infection and monitor therapy.
Glossary Term
The process of exchange of genetic material between autonomous replicons, which depends on regions of extensive sequence homology between the participating DNA strands. This process involves double-strand breakage of one participant, resection of the break, and strand invasion, followed by formation, displacement and resolution of the Holliday junction. This process is involved in repairing broken DNA and creating combinations of genes that may be unique from the parent duplexes. Disruptions in this process can result in inviability, premature aging and predisposition to cancers and degenerative diseases.
Glossary Term
Having two identical allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.
