AP BIOLOGY

Detailed explanation-1: -Tumors and tumor-derived cell lines contain polyploid giant cells with significantly elevated genomic content, often with multiple nuclei.

Detailed explanation-2: -Liver cells, muscle fibers, and osteoclasts are all normal cells that often have more than one nucleus. Cancerous cells and those infected with viruses can also have multiple nuclei at times.

Detailed explanation-3: -In addition, cancer cells often have an abnormal shape-both the cell and the nucleus (the “brain” of the cell.) The nucleus appears both larger and darker than normal cells. The reason for the darkness is that the nucleus of cancer cells contains excess DNA.
