Question

1. this diagram represents human chromosome 11. the labeled areas represent the approximate locations of genetic changes associated with specific conditions. chromosome 11 sickle cell disease t - cell leukemia b - cell leukemia the changes that cause the labeled conditions originate in: a. proteins b. genes c. enzymes d. subunits 3. which of these characteristics applies to individuals with sickle cell disease? a. their hemoglobin molecules carry extra oxygen. b. their dna sticks to itself due to changes in amino acid molecules. c. their hemoglobin molecules clump together.

Explanation:

For question 2, genetic - related conditions like sickle cell disease and leukemias are caused by changes in genes which are segments of DNA on chromosomes. For question 3, in sickle - cell disease, abnormal hemoglobin molecules clump together, deforming red blood cells into a sickle shape.

Answer:

1. b. genes
2. c. Their hemoglobin molecules clump together.
