How do we know that malignant tumors arise from a single cell that contains mutations?
A
By detecting the presence of multiple cell types in a tumor
B
By identifying the absence of mutations in surrounding healthy tissue
C
By analyzing the genetic uniformity of cancer cells within a tumor
D
By observing the rapid growth rate of cancer cells
Verified step by step guidance1
Understand that malignant tumors are characterized by uncontrolled cell growth due to genetic mutations.
Recognize that if a tumor arises from a single cell, all the cancer cells within the tumor should have the same genetic mutations.
Analyze the genetic material of cancer cells within a tumor to check for uniformity in mutations.
Compare the genetic profile of cancer cells with that of surrounding healthy tissue to confirm the absence of these mutations in normal cells.
Conclude that the genetic uniformity of cancer cells within a tumor supports the idea that they originated from a single mutated cell.
