CRISPR Therapeutics AG is a Swiss–American biotechnology company headquartered in Zug, Switzerland.It was one of the first companies formed to utilize the CRISPR gene editing platform to develop medicines for the treatment of various rare and common diseases.
Whereas a genome sequence lists the order of every DNA base in a genome, a genome map identifies the landmarks. A genome map is less detailed than a genome sequence and aids in navigating around the genome. [77] [78] An example of a variation map is the HapMap being developed by the International HapMap Project.
A Plasmodium knowlesi merozoite attaching to a red blood cell. P. knowlesi largely resembles other Plasmodium species in its cell biology. Its genome consists of 23.5 megabases of DNA separated into 14 chromosomes. [5] It contains approximately 5200 protein-coding genes, 80% of which have orthologs present in P. falciparum and P. vivax.

Sickle-cell and malaria. As a recessive gene, Sickle-cell disease is only present if homozygous, with no dominant gene to beat them out. Sickle-cell disease, originating in people living in tropical areas where malaria is prevalent, is a hereditary blood disorder characterized by rigid, sickle-shaped red blood cells. The unusual shape and ...

Sickle cell trait causes a change in the haemoglobin molecule in the blood. Normally, red blood cells have a very flexible, biconcave shape that allows them to move through narrow capillaries ; however, when the modified haemoglobin S molecules are exposed to low amounts of oxygen, or crowd together due to dehydration, they can stick together ...
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.
