- Acute lymphocytic leukemia (ALL) is a kind of blood and bone marrow malignancy. Blood cells are generated in the spongy tissue inside the bones.
- Acute lymphocytic leukemia gets its name from the fact that it advances quickly and produces immature blood cells rather than mature ones.
- Acute lymphoblastic leukemia in children is more frequent than other cancers, however it is curable in a significant portion of cases. Adult survival rates are lower, although they are rising.
- ALL has a 5-year relative survival rate of 68.8%. 90 percent of children and 30 to 40 percent of adults are included in the statistics, respectively.

<u>Answer</u>: Appear to function in similar ways across diverse groups of organisms.
<u>Explanation</u>:
- The <em>hox</em> genes are a subset of homeotic genes.
- The function of the hox genes is to control the development of the body plan of an individual during the embryonic stage.
- Thus, the basic body form of an organism is laid down with the help of these genes.
- <em>These genes are present in many different species from fruit fly to mice to humans</em>.
- The reason that they are present in different organisms is that there was a common ancestor that possessed the hox gene cluster and then the genes were passed on to different vertebrates. However, the slight changes that have occurred in these genes are due to duplication events.
In humans a gene that has been identified as causing a type of skin cancer is the
