  2. Plasmodium falciparum - Wikipedia

    en.wikipedia.org/wiki/Plasmodium_falciparum

    Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. [2] The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria.

  3. Human genetic variation - Wikipedia

    en.wikipedia.org/wiki/Human_genetic_variation

    The study of human genetic variation has evolutionary significance and medical applications. It can help scientists reconstruct and understand patterns of past human migration. In medicine, study of human genetic variation may be important because some disease-causing alleles occur more often in certain population groups.

  4. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR-Cas9. CRISPR gene editing (CRISPR, pronounced / ˈ k r ɪ s p ə r / "crisper", refers to "clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.

  5. Evolutionary pressure - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_pressure

    The malaria parasite can exert a selective pressure on human populations. This pressure has led to natural selection for erythrocytes carrying the sickle cell hemoglobin gene mutation (Hb S)—causing sickle cell anaemia—in areas where malaria is a major health concern, because the condition grants some resistance to this infectious disease. [8]

  6. Hemoglobin A2 - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_A2

    Hemoglobin A2 (HbA 2) is a normal variant of hemoglobin A that consists of two alpha and two delta chains (α 2 δ 2) and is found at low levels in normal human blood.Hemoglobin A2 may be increased in beta thalassemia or in people who are heterozygous for the beta thalassemia gene.

  7. Duffy antigen system - Wikipedia

    en.wikipedia.org/wiki/Duffy_antigen_system

    It was noted in the 1920s that black Africans had some intrinsic resistance to malaria, but the basis for this remained unknown. The Duffy antigen gene was the fourth gene associated with the resistance after the genes responsible for sickle cell anaemia, thalassemia and glucose-6-phosphate dehydrogenase.

  8. Henrietta Lacks - Wikipedia

    en.wikipedia.org/wiki/Henrietta_Lacks

    Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [1] was an African-American woman [4] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [A] and one of the most important cell lines in medical research.

  9. Chromosome 11 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_11

    Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells. The shorter arm (p arm) is termed 11p while the longer arm (q arm) is 11q.
