Respuesta :
The answer should be C because the DNA in the genes is what causes genetic mutations. The sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.
Answer: option C They study chromosomes that contain genes, which are DNA segments.
Explanation: chromosomes carry genetic information which is stored in genes. Genes are DNA segments which are located on the chromosomes. Genes codes for a certain protein which performs a particular function.
Change in the original DNA sequence leads to genetic mutations. So in order to study genetic mutations, scientists must study genetic material.
