An Rh-positive father carries two genes for the Rh antigen in his cells. He has a child with an Rh-negative mother. What are the chances that the child will be Rh positive? a) 0% b) 25% c) 50% d) 100% e) Impossible to determine from ...
What proteins are involved in the control of the cell cycle? What would the amino acids on the outside of the transmembrane protein be, given that they are exposed to fatty acid chains, as opposed to those located on the inside and exposed to glucose? A)...
aMuch of what is known about the genetic basis of high-altitude adaptation in natural populadons comes from studies that have taken a ‘candidate gene’approach, and many of these studies have focused on sequence variation in hemoglobin genes. Several of these have become well-known case ...
Beta-thalassemia occurs when at least one of the two inherited beta hemoglobin genes are defective. This form of thalassemia occurs most often in persons of “Mediterranean (Greek, Italian, and Middle Eastern), Asian, or African origin or ancestry.” (NHLBI). The severity of this form of ...
Thalassemias are also inherited. They happen when a faulty gene causes the body to make too few red blood cells and hemoglobin. Hemoglobin is the iron-rich protein in red cells that carries oxygen. Some thalassemias are more severe than others. Some people with thalassemia don’t need treatme...
A child is given 2 abnormal genes for hemoglobin, 1 from each parent.What are the signs and symptoms of SCD?The following symptoms may come and go, or may happen during a sickle cell crisis:Low energy Pain anywhere in your body Pale skin Headaches Shortness of breathHow is SCD diagnosed...
Proteins are the workhorses of biology: for example, the proteins myosin and actin make up muscle, the protein collagen is part of our connective tissue, hemoglobin is the protein that transports oxygen in our blood and makes it red, and so forth. Insulin is a small protein that functions ...
Human hemoglobin genes are located in α and β globin gene clusters in chromosomes 16 and 11, respectively. Different types of hemoglobin are synthesized according to the stage of development with fetal hemoglobin (α(2)γ(2)) (Hb F) being the main hemoglobin in the fetal period. After...
What are genes which encode proteins needed for conjugation called? What is the name of the molecule that is the primary (starting) substrate for glycolysis? What is the entry mechanism of only enveloped viruses into host cells called?
Genes and Alleles: Genes are sections of DNA that code for our traits, such as the genes for eye color or specific proteins made in our body, like hemoglobin. Alleles are different versions of genes that create variation in our traits, such as the different eye colors we observe. ...
