The A-blood type allele and the B-blood type allele differ from each other based upon which of the following? chromosomal location DNA sequence phosphorylation of the protein mechanism of translation

(a) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information. (b) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.

Duplicated chromosomes are physically connected along an area of the chromosome known as the

A change in what type of cell is most likely to cause a mutation that can be inherited?

Define copy number variation

DNA replication is semi-conservative; a copy of each strand is made and the new set is inherited to one cell and the old set is inherited to the second cell.  True False

Explain what each genetic code means  #1- #2- #3- #4

A 30 - year - old woman was undergoing therapy for b-thalassemia,a recessive trait caused by absence of or reduced synthesis ofthe hemoglobin b chain, a subunit of the oxygen-carrying moleculein red blood cells. In this condition, red blood cells are rapidlydestroyed, freeing a large amount of iron, which is deposited in tissuesand organs. The blood transfusions the patient had received every twoor three weeks since the age of 7 to stave off anemia were furtheraggravating iron buildup. Her major organs were showing damage, andshe was in danger of death from cardiac disease. Her physician suggestedthat she consider undergoing a hematopoietic (bone marrow)stem cell transplant (HSCT). Since these stem cells give rise to redblood cells, such a transplant could potentially restore her health. Whilethis might seem like an easy decision, it is not. Advanced cases havea high risk (almost 30 percent) for transplantation-related death. At thispoint, the woman is faced with a difficult and…
