RBCs can get stuck inside blood vessels. This can stop or slow blood flow, and prevent oxygen from getting to tissues. When this happens, it is called a sickle cell crisis. SCD also causes RBCs break apart and die faster than healthy RBCs. This causes low red blood cell levels (anemia)...
When this happens, it is called a sickle cell crisis. SCD also causes RBCs break apart and die faster than healthy RBCs. This causes low red blood cell levels (anemia).What causes SCD?SCD is passed from parents to a child. A child is given 2 abnormal genes for hemoglobin, 1 from ...
Genes passed from parents to children cause it. They affect hemoglobin, a blood protein. Sickle cell anemia, which is severe, happens if you inherit two copies of the sickle cell gene -- one from each parent. Sickle cell trait happens if you have one copy plus one normal gene. That mean...
In centrifuged blood the white layer of the blood is called what? What are gustatory cells? Explain the genetic basis of sickle cell anemia. What are the characteristics of red blood cells? What is a lipoprotein? What is a Chylomicron?
The system is made up of two key parts: a CRISPR-associated (Cas) nuclease, which binds and cuts DNA, and a guide RNA sequence (gRNA), which directs the Cas nuclease to its target. It was discovered in bacterial immune systems, where it cuts the DNA of invading viruses, called bacteri...
Stem cells are the “foundational” cells of the body – every tissue and organ in the body comes from stem cells. Another way to think of stem cells is as a “blank slate”: they don’t have a specialized purpose. But they have the potential to become any other type of cell: brain...
Embryonic stem cells are often called human pluripotent stem cells, which can produce many different cell types. This is in contrast to "multipotent" stem cells, which can only differentiate into a limited number of cell types. Pluripotent stem cells are unspecialized and do not possess the speci...
What is the most common cause of hemolytic anemia? The most common intrinsic causes of hemolytic anemia are thalassemia and sickle cell disease. Autoimmune disorders are believed to be the most common extrinsic cause. Other hemolysis causes include the following: Genetic causes of hemolytic anemia S...
How does the white blood cell count of abnormal blood smear differ from that of a normal blood smear? What is sickle cell anemia? An individual is suffering from sickle cell anemia. Describe how their test results (hematocrit, hemoglobin, blood smear) might differ, if at all, ...
My guest today is Joseph Henrich, a professor at Harvard, and an expert on the evolution of human cooperation and culture. I am a big fan of his book, “The Secret of Our Success” and he just published a new one called the Weirdest People in the World about people who fall under ...
