Question

How are tumor cells different from normal cells

Answer 1

The correct option is: b. mitosis is not regulated in tumor cells. Cancer cells are malignant tumor cells and  cancer is a disease of mitosis where the cell divides uncontrollably.

The tumor cells use mitosis to replicate and and cell cycle checkpoints are ignored so the mitosis is unregulated. So option c.  tumor cells use meiosis to replicate is incorrect.

Tumor cells contain abnormal number of chromosomes so option d. is incorrect as it contains chromosomes.

Due to aneuploidy of tumor cells it cannot be specifically haploid or diploid so option a is incorrect.

Answer 2

The mitosis is not regulated in the tumor cell that makes it different from a normal cell. The other characteristics are cell shape, nucleus shape, chromatin, and growth rate, etc.that make it different from a normal cell.

Further Explanation:

The difference between normal cells and tumor cells are listed in table 1 attached below.
